Visitors to Syria must obtain a visa from one of the Syrian diplomatic missions in advance, unless they are a national of a visa-exempt country or a country whose citizens are eligible to obtain visas on arrival.
 Before the start of protests, hostilities and conflicts and the start of the devastating Civil war in Syria in 2011, citizens of many Asian, European, African and American countries could visit Syria without a visa or get a visa on arrival, gradually Syria began to cancel visa-free entry and visa on arrival for many countries, and in 2014 the Syrian authorities officially announced the introduction of a visa regime for all countries. However, until now, citizens of some states can de facto enter Syria without a visa or receive a visa on arrival. The visa policy of Syria is now extremely unstable, and there is no exact data on the visa policy of this country. This data is taken from open sources and may become outdated or irrelevant. When entering Syria, the Syrian authorities ask to obtain a Syrian visa in advance by contacting one of the 
country's diplomatic missions in the world.
 Until 2014, citizens of the former Soviet republics of the USSR (excluding the Baltic republics), Iran, some Asian, African, European, American countries, and almost all countries of the Arab world did not need a visa to enter Syria. According to IATA, which provides information provided by national governments, despite the Syrian government's officially stated need to obtain a visa in advance, a visa on arrival is still de facto valid for citizens of Armenia, Azerbaijan, Belarus, Egypt, Iran, Kazakhstan, Kyrgyzstan, Russia, Tajikistan, Turkmenistan and Uzbekistan, but after the intensification of the Civil war, some citizens of these countries are denied a visa on arrival “for security reasons” and ask citizens of these countries to obtain a Syrian visa in advance:

 Before the outbreak of the Syrian civil war in 2011, Syria was one of the most popular tourist destinations in the Middle East. Tourism and the entry of foreigners into Syria in general began to develop especially since the late 1990s. Foreigners entered Syria not only to visit relatives or friends, but also for tourism, medical treatment and pilgrimage to Islamic and Christian sites, as well as for trade, as Syria became an important trading hub for the surrounding countries. Syria was popular especially for citizens of Turkey, Iran, almost all countries of the Arab world, Europe and South Asia, as well as for almost all countries of the Post-Soviet space as a budget travel option and a shopping point for merchants.
 The list does not include Russian citizens who entered Syria through third countries, as well as through the uncontrolled borders of Syria by the official government of the Syrian Arab Republic. Especially between 2011 and 2016, the real number of Russian citizens who entered Syria was several times more.
