Travel visa
A visa (from the Latin "charta visa", meaning "paper that has been seen") is a conditional authorization granted by a polity to a foreigner that allows them to enter, remain within, or to leave its territory. Visas typically include limits on the duration of the foreigner's stay, areas within the country they may enter, the dates they may enter, the number of permitted visits, or if the individual has the ability to work in the country in question. Visas are associated with the request for permission to enter a territory and thus are, in most countries, distinct  from actual formal permission for an alien to enter and remain in the country. In each instance, a visa is subject to entry permission by an immigration official at the time of actual entry and can be revoked at any time. Visa evidence most commonly takes the form of a sticker endorsed in the applicant's passport or other travel document but may also exist electronically. Some countries no longer issue physical visa evidence, instead recording details only in immigration databases. Historically, immigration officials were empowered to permit or reject entry of visitors on arrival at the frontiers. If permitted  entry, the official would issue a visa, when required, which would be a stamp in a passport. Today, travellers wishing to enter another country must often apply in advance for what is also called a visa, sometimes in person at a consular office, by post, or over the internet. The modern visa may be a sticker or a stamp in the passport, an electronic record of the authorization, or a separate document which the applicant can print before entering and produce on entry to the visited polity. Some countries do not require visitors to apply for a visa in advance  for short visits. Visa applications in advance of arrival give countries a chance to consider the applicant's circumstances, such as financial security, reason for travel, and details of previous visits to the country. Visitors may also be required to undergo and pass security or health checks upon arrival at the port of entry. Some polities which restrict emigration require individuals to possess an exit visa to leave the polity. These exit visas may be required for citizens, foreigners, or both, depending on the policies of the polity concerned. Unlike ordinary visas, exit visas are often seen as an illegitimate  intrusion on individuals' right to freedom of movement. Imposition of an exit visa requirement may be seen to violate customary international law, as the right to leave any country is provided for in the Universal Declaration of Human Rights. Uniquely, the Norwegian special territory of Svalbard is an entirely visa-free zone under the terms of the Svalbard Treaty. Some countries—such as those in the Schengen Area—have agreements with other countries allowing each other's citizens to travel between them without visas. The World Tourism Organization announced that the number of tourists requiring a visa before travelling was  at its lowest level ever in 2015. History. In western Europe in the late 19th century and early 20th century, passports and visas were not generally necessary for moving from one country to another. The relatively high speed and large movements of people travelling by train would have caused bottlenecks if regular passport controls had been used. Passports and visas became usually necessary as travel documents only after World War I. Hitherto, passports and visas were usually the same type of travel documents. In the modern world, visas have become separate secondary travel documents, with passports acting as the primary  travel documents. Conditions of issue. Some visas can be granted on arrival or by prior application at the country's embassy or consulate, or through a private visa service specialist who is specialized in the issuance of international travel documents. These agencies are authorized by the foreign authority, embassy, or consulate to represent international travellers who are unable or unwilling to travel to the embassy and apply in person. Private visa and passport services collect an additional fee for verifying customer applications, supporting documents, and submitting them to the appropriate authority. If there is no embassy or consulate in one 's home country, then one would have to travel to a third country (or apply by post) and try to get a visa issued there. Alternatively, in such cases visas may be pre-arranged for collection on arrival at the border. The need or absence of need of a visa generally depends on the citizenship of the applicant, the intended duration of the stay, and the activities that the applicant may wish to undertake in the country he or she visits; these may delineate different formal categories of visas, with different issue conditions. The issuing authority, usually a branch of  the country's foreign ministry or department (e.g. U.S. State Department), and typically consular affairs officers, may request appropriate documentation from the applicant. This may include proof that the applicant is able to support him or herself in the host country (lodging, food), proof that the person hosting the applicant in his or her home really exists and has sufficient room for hosting the applicant, proof that the applicant has obtained health and evacuation insurance, etc. Some countries ask for proof of health status, especially for long-term visas; some countries deny such visas to persons with certain illnesses, such  as AIDS. The exact conditions depend on the country and category of visa. Notable examples of countries requiring HIV tests of long-term residents are Russia and Uzbekistan. In Uzbekistan, however, the HIV test requirement is sometimes not strictly enforced. Other countries require a medical test that includes an HIV test, even for a short-term tourism visa. For example, Cuban citizens and international exchange students require such a test approved by a medical authority to enter Chilean territory. The issuing authority may also require applicants to attest that they have no criminal convictions, or that they do not participate  in certain activities (like prostitution or drug trafficking). Some countries will deny visas if passports show evidence of citizenship of, or travel to, a country that is considered hostile by that country. For example, some Arabic-oriented countries will not issue visas to nationals of Israel and those whose passports bear evidence of visiting Israel. Many countries frequently demand strong evidence of intent to return to the home country, if the visa is for a temporary stay, due to potential unwanted illegal immigration. Proof of ties to the visa applicant's country of residence is often demanded to demonstrate a  sufficient incentive to return. This can include things such as documented evidence of employment, bank statements, property ownership, and family ties. Types. Each country typically has a multitude of categories of visas with various names. The most common types and names of visas include: By purpose. Transit visas. For passing through the country of issue to a destination outside that country. Validity of transit visas are usually limited by short terms such as several hours to ten days depending on the size of the country or the circumstances of a particular transit itinerary. Short-stay or visitor visas. For short  visits to the visited country. Many countries differentiate between different reasons for these visits, such as: Long-stay visas. Visas valid for long term stays of a specific duration include: Immigrant visas. Granted for those intending to settle permanently in the issuing country (obtain the status of a permanent resident with a prospect of possible naturalization in the future): Official visas. These are granted to officials doing jobs for their governments, or otherwise representing their countries in the host country, such as the personnel of diplomatic missions. By method of issue. Normally visa applications are made at and collected from  a consulate, embassy, or other diplomatic mission. On-arrival visas. Also known as visas on arrival (VOA), they are granted at a port of entry. This is distinct from visa-free entry, where no visa is required, as the visitor must still obtain the visa on arrival before proceeding to immigration control. Electronic visas. An electronic visa (e-Visa or eVisa) is stored in a computer and is linked to the passport number so no label, sticker, or stamp is placed in the passport before travel. The application is done over the internet, and the receipt acts as a visa , which can be printed or stored on a mobile device. Russia maintains an eVisa program for visitors from certain countries arriving to Russian Far East, Saint Petersburg, Leningrad Region and Kaliningrad Region. And will introduce a single electronic visa from 1 January 2021. Authorities of Belarus, Chad, Republic of the Congo, Democratic Republic of the Congo, Equatorial Guinea, Ghana, Japan, Kazakhstan, Liberia, South Africa, and Tunisia have announced plans to introduce electronic visas in the future. These lists are not exhaustive. Some countries may have more detailed classifications of some of these categories reflecting the nuances of their respective geographies , social conditions, economies, international treaties, etc. In some countries that exempt visitors of certain nationalities from visa requirements, it is still necessary to receive prior authorization before arriving by air. These travel authorizations typically last for several years, and can be used multiple times. Airlines are required to verify that all passengers without a visa have obtained authorization before departure, or risk fines and the cost of a returning a passenger to their country of origin. Entry and duration period. Visas can also be "single-entry", which means the visa is cancelled as soon as the holder leaves the country ; "double-entry", or "multiple-entry", which permits double or multiple entries into the country with the same visa. Countries may also issue re-entry permits that allow temporarily leaving the country without invalidating the visa. Even a business visa will normally not allow the holder to work in the host country without an additional work permit. Once issued, a visa will typically have to be used within a certain period of time. In some countries, the validity of a visa is not the same as the authorized period of stay. The visa validity then indicates the time period when the  entry is permitted into the country. For example, if a visa has been issued to begin on January 1 and to expire on March 30, and the typical authorized period of stay in a country is 90 days, then the 90-day authorized stay starts on the day the passenger enters the country (entrance has to be between 1 January and 30 March). Thus, the latest day the traveller could conceivably stay in the issuing country is 1 July (if the traveller entered on 30 March). This interpretation of visas is common in the Americas. With other countries, a person  may not stay beyond the period of validity of their visa, which is usually set within the period of validity of their passport. The visa may also limit the total number of days the visitor may spend in the applicable territory within the period of validity. This interpretation of visa periods is common in Europe. Once in the country, the validity period of a visa or authorized stay can often be extended for a fee at the discretion of immigration authorities. Overstaying a period of authorized stay given by the immigration officers is considered illegal immigration even if the visa  validity period isn't over (i.e., for multiple entry visas) and a form of being "out of status" and the offender may be fined, prosecuted, deported, or even blacklisted from entering the country again. Entering a country without a valid visa or visa exemption may result in detention and removal (deportation or exclusion) from the country. Undertaking activities that are not authorized by the status of entry (for example, working while possessing a non-worker tourist status) can result in the individual being deemed liable for deportation—commonly referred to as an illegal alien. Such violation is not a violation  of a visa, despite the common misuse of the phrase, but a violation of status; hence the term "out of status". Even having a visa does not guarantee entry to the host country. The border crossing authorities make the final determination to allow entry, and may even cancel a visa at the border if the alien cannot demonstrate to their satisfaction that they will abide by the status their visa grants them. Some countries that do not require visas for short stays may require a long-stay visa for those who intend to apply for a residence permit. For  example, the EU does not require a visa of citizens of many countries for stays under 90 days, but its member states require a long-stay visa of such citizens for longer stays. Visa extensions. Many countries have a mechanism to allow the holder of a visa to apply to extend a visa. In Denmark, a visa holder can apply to the Danish Immigration Service for a Residence Permit after they have arrived in the country. In the United Kingdom, applications can be made to UK Visas and Immigration. In certain circumstances, it is not possible for the holder of  the visa to do this, either because the country does not have a mechanism to prolong visas or, most likely, because the holder of the visa is using a short stay visa to live in a country. Visa run. Some foreign visitors sometimes engage in what is known as a "visa run": leaving a country—usually to a neighbouring country—for a short period just before the permitted length of stay expires, then returning to the first country to get a new entry stamp in order to extend their stay ("reset the clock"). Despite the name, a visa run is  usually done with a passport that can be used for entry without a visa. Visa runs are frowned upon by immigration authorities as such acts may signify that the foreigner wishes to reside permanently and might also work in that country; purposes that visitors are prohibited from engaging in and usually require an immigrant visa or a work visa. Immigration officers may deny re-entry to visitors suspected of engaging in prohibited activities, especially when they have done repeated visa runs and have no evidence of spending reasonable time in their home countries or countries where they have the right  to reside and work. To combat visa runs, some countries have limits on how long visitors can spend in the country without a visa, as well as how much time they have to stay out before "resetting the clock". For example, Schengen countries impose a maximum limit for visitors of 90 days in any 180-day period. Some countries do not "reset the clock" when a visitor comes back after visiting a neighbouring country. For example, the United States does not give visitors a new period of stay when they come back from visiting Canada, Mexico, or the Caribbean; instead  they are readmitted to the United States for the remaining days granted on their initial entry. Some other countries, e.g. Thailand, allow visitors who arrive by land from neighbouring countries a shorter length of stay than those who arrive by air. In some cases, a visa run is necessary to activate new visas or change the immigration status of a person. An example would be leaving a country and then returning immediately to activate a newly issued work visa before a person can legally work. Visa refusal. In general, an applicant may be refused a visa if they do not  meet the requirements for admission or entry under that country's immigration laws. More specifically, a visa may be denied or refused when the applicant: Even if a traveller does not need a visa, the aforementioned criteria can also be used by border control officials to refuse the traveller's entry into the country in question. Visa policies. The main reasons states impose visa restrictions on foreign nationals are to curb illegal immigration, security concerns, and reciprocity for visa restrictions imposed on their own nationals. Typically, nations impose visa restrictions on citizens of poorer countries, along with politically unstable and  undemocratic ones, as it is considered more likely that people from these countries will seek to illegally immigrate. Visa restrictions may also be imposed when nationals of another country are perceived as likelier to be terrorists or criminals, or by autocratic regimes that perceive foreign influence to be a threat to their rule. According to Professor Eric Neumayer of the London School of Economics: "The poorer, the less democratic, and the more exposed to armed political conflict the target country is, the more likely that visa restrictions are in place against its passport holders. The same is true for countries  whose nationals have been major perpetrators of terrorist acts in the past". Some countries apply the principle of reciprocity in their visa policy. A country's visa policy is called 'reciprocal' if it imposes visa requirement against citizens of all the countries that impose visa requirements against its own citizens. The opposite is rarely true: a country rarely lifts visa requirements against citizens of all the countries that also lift visa requirements against its own citizens, unless a prior bilateral agreement has been made. A fee may be charged for issuing a visa; these are often also reciprocal—hence, if  country A charges country B's citizens US$50 for a visa, country B will often also charge the same amount for country A's visitors. The fee charged may also be at the discretion of each embassy. A similar reciprocity often applies to the duration of the visa (the period in which one is permitted to request entry of the country) and the number of entries one can attempt with the visa. Other restrictions, such as requiring fingerprints and photographs, may also be reciprocated. Expedited processing of the visa application for some countries will generally incur additional charges. Government  authorities usually impose administrative entry restrictions on foreign citizens in three ways - countries whose nationals may enter without a visa, countries whose nationals may obtain a visa on arrival, and countries whose nationals require a visa in advance. Nationals who require a visa in advance are usually advised to obtain them at a diplomatic mission of their destination country. Several countries allow nationals of countries that require a visa to obtain them online. The following table lists visa policies of all countries by the number of foreign nationalities that may enter that country for tourism without a visa or by  obtaining a visa on arrival with normal passport. It also notes countries that issue electronic visas to certain nationalities. Symbol "+" indicates a country that limits the visa-free regime negatively by only listing nationals who require a visa, thus the number represents the number of UN member states reduced by the number of nationals who require a visa and "+" stands for all possible non-UN member state nationals that might also not require a visa. "N/A" indicates countries that have contradictory information on its official websites or information supplied by the Government to IATA. Some countries that  allow visa on arrival do so only at a limited number of entry points. Some countries such as the European Union member states have a qualitatively different visa regime between each other as it also includes freedom of movement. The following table is current . Source: Visa exemption agreements. Possession of a valid visa is a condition for entry into many countries, and exemption schemes exist. In some cases visa-free entry may be granted to holders of diplomatic passports even as visas are required by normal passport holders ("see: Passport"). Some countries have reciprocal agreements such that a visa is  not needed under certain conditions, e.g., when the visit is for tourism and for a relatively short period. Such reciprocal agreements may stem from common membership in international organizations or a shared heritage: Other countries may unilaterally grant visa-free entry to nationals of certain countries to facilitate tourism, promote business, or even to cut expenses on maintaining consular posts abroad. Some of the considerations for a country to grant visa-free entry to another country include (but are not limited to): To have a smaller worldwide diplomatic staff, some countries rely on other country's (or countries') judgments when  issuing visas. For example, Mexico allows citizens of all countries to enter without Mexican visas if they possess a valid American visa that has already been used. Costa Rica accepts valid visas of Schengen/EU countries, Canada, Japan, South Korea, and the United States (if valid for at least 3 months on date of arrival). The ultimate example of such reliance is Andorra, which imposes no visa requirements of its own because it has no international airport and is inaccessible by land without passing through the territory of either France or Spain and is thus "protected" by the Schengen visa  system. Visa-free travel between countries also occurs in all cases where passports (or passport-replacing documents such as laissez-passer) are not needed for such travel. ("For examples of passport-free travel, see International travel without passports".) As of 2019, the "Henley & Partners" passport index ranks the Japanese, Singaporean, and South Korean passports as the ones with the most visa exemptions by other nations, allowing holders of those passports to visit 189 countries without obtaining a visa in advance of arrival. However, the Passport Index ranks the United Arab Emirates passport as the one with the most visa exemptions  by other nations, allowing holders of this passport to visit 173 countries without obtaining a visa in advance of arrival. Common visas. Normally, visas are valid for entry only into the country that issued the visa. Countries that are members of regional organizations or party to regional agreements may, however, issue visas valid for entry into some or all of the member states of the organization or agreement: Possible common visa schemes. Potentially, there are new common visa schemes: Previous common visa schemes. These schemes no longer operate. Exit visas. Exit visas may be required to leave some countries. Many  countries limit the ability of individuals to leave in certain circumstances, such as those with outstanding legal proceedings or large government debts. Despite this, the term "exit visa" is generally limited to countries that systematically restrict departure, where the right to leave is not automatic. Imposing a systematic requirement for exit permission may be seen to violate the right to freedom of movement, which is found in the UDHR and forms part of customary international law. Countries implementing exit visas vary in who they require to obtain one. Some countries permit the free movement of foreign nationals while restricting their  own citizens. Others may limit the exit visa requirement to resident foreigners in the country on work visas, such as in the Kafala system. Asia. Iraq, Kuwait, Lebanon, Oman, Saudi Arabia, and the United Arab Emirates all have an exit visa requirement for alien foreign workers. This is part of their "kafala" work visa sponsorship system. Consequently, at the end of a foreign worker's employment period, the worker must secure clearance from their employer stating that the worker has satisfactorily fulfilled the terms of their employment contract or that the worker's services are no longer needed. The exit  visa can also be withheld if there are pending court charges that need to be settled or penalties that have to be meted out. In September 2018, Qatar lifted the exit visa requirement for most workers. Persons are generally free to leave Israel, except for those who are subject to a stay of exit order. Nepal requires its citizens emigrating to the United States on an H-1B visa to present an exit permit issued by the Nepali Ministry of Labour. This document is called a work permit and needs to be presented to Nepali immigration to leave Nepal. Uzbekistan was  the last remaining country of the former USSR that required an exit visa, which was valid for a two-year period. The practice was abolished in 2019. There had been explicit United Nations complaint about this practice. North Korea requires that its citizens obtain an exit visa stating the traveller's destination country and time to be spent abroad before leaving the country. Additionally, North Korean authorities also require North Korean citizens obtain a re-entry visa from a North Korean embassy or North Korean mission abroad before being allowed back into North Korea. The government of the People's  Republic of China requires its citizens to obtain a two-way permit, issued by the People's Republic of China's authorities, prior to visiting Hong Kong or Macau. The two-way permit is a "de facto" exit visa for Hong Kong- or Macau-bound trips for citizens of the People's Republic of China. Singapore operates an Exit Permit scheme in order to enforce the national service obligations of its male citizens and permanent residents. Requirements vary according to age and status: Taiwan and South Korea also require male citizens who are older than a certain age but have  not fulfilled their military duties to register with local Military Manpower Administration office before they pursue international travels, studies, business trips, and/or performances. Failure to do so is a felony in those countries and violators would face up to 3 years of imprisonment. Europe. During the Fascist period in Italy, an exit visa was required from 1922 to 1943. Nazi Germany required exit visas from 1933 to 1945. The Soviet Union and its Warsaw Pact allies required exit visas both for emigration and for those who wanted to leave the Soviet Union for a shorter period. Some countries, including the  Czech Republic, require that an alien who needs a visa on entry be in possession of a valid visa upon exit. To satisfy this formal requirement, exit visas sometimes need to be issued. Russia requires an exit visa if a visitor stays past the expiration date of their visa. They must then extend their visa or apply for an exit visa and are not allowed to leave the country until they show a valid visa or have a permissible excuse for overstaying their visa (e.g., a note from a doctor or a hospital explaining an illness, missed flight, lost or  stolen visa). In some cases, the Ministry of Foreign Affairs can issue a return-Home certificate that is valid for ten days from the embassy of the visitor's native country, thus eliminating the need for an exit visa. A foreign citizen granted a temporary residence permit in Russia needs a temporary resident visa to take a trip abroad (valid for both exit and return). It is also colloquially called an "exit visa". Not all foreign citizens are subject to that requirement. Citizens of Germany, for example, do not require this exit visa. In March 2021, during the COVID-19 pandemic , the United Kingdom required everyone leaving England to fill out an exit form detailing their address, passport number, destination, and reason to travel. Permitted reasons to travel included for work or volunteering, education, medical or compassionate reasons such as weddings and funerals. Travellers may be required to carry evidence to support their reason to travel. Americas. The government of Cuba announced in October 2012 its plans to remove exit visa requirements effective 14 January 2013, albeit with some exceptions. Guatemala requires any foreigner who is a permanent resident to apply for a multiple 5-year exit visa. United States. The  United States of America does not require exit visas. Since 1 October 2007, however, the U.S. government requires "all" foreign and U.S. nationals "departing" the United States by air to hold a valid passport (or certain specific passport-replacing documents). Even though travellers might not require a passport to enter a certain country, they "will" require a valid passport booklet (booklet only, U.S. Passport Card not accepted) to depart the United States in order to satisfy the U.S. immigration authorities. Exemptions to this requirement to hold a valid passport include: In addition, green card holders and certain other aliens must  obtain a certificate of compliance (also known as a "sailing permit" or "departure permit") from the Internal Revenue Service proving that they are up-to-date with their US income tax obligations before they may leave the country. While the requirement has been in effect since 1921, it has not been stringently enforced, but in 2014 the House Ways and Means Committee has considered beginning to enforce the requirement as a way to increase tax revenues. Australia. Australia, citing COVID-19 concerns, in 2020 banned outward travel by both Australian citizens and permanent residents, unless they requested and were granted an  exemption. In August 2021 this ban was extended to people who are ordinarily resident in countries other than Australia as well. Exceptions apply to business travel and travel for "compelling reasons" for three months or longer, among others. On 1 November 2021, after 20 months, the exit permit system was scrapped and New South Wales and Victoria officially re-opened their borders in addition to ending quarantine requirements on arrival for fully vaccinated individuals. However, on 27 November 2021, 72-hour quarantine requirements were reinstated over concerns about the SARS-CoV-2 Omicron variant. Visa restrictions. World Tourism Organization. The World  Tourism Organization (UNWTO) of the United Nations has issued various "Visa Openness Report"s.
