Title: Economy of Cuba
Content:  From 1994 until 2021, Cuba had two official currencies: the national peso (or CUP) and the convertible peso (or CUC, often called "dollar" in the spoken language). In January 2021, however, a long-awaited process of currency unification began, with Cuban citizens being given six months to exchange their remaining CUCs at a rate of one to every 24 CUPs. In 1994 the possession and use of US dollars was legalised, and by 2004 the US dollar was in widespread use in the country. To capture the hard currency flowing into the island through tourism and remittances – estimated at $500–800 million annually – the government set up state-run "dollar stores" throughout Cuba that sold "luxury" food, household and clothing items, compared with basic necessities, which could be bought using national pesos. As such, the standard of living diverged between those who had access to 
Title: Tourism in Cuba
Content:  Cuba remains legal for US citizens who meet certain requirements. As of 2019, Americans are legally allowed to go to Cuba with an OFAC self-reporting General License if they meet the requirements for one of the 12 categories of legal travel (such as family visits, religious purposes, journalistic work, etc.) Independent travelers to Cuba can qualify for the "Support for the Cuban People" category by maintaining a full-time schedule of activities that fulfill this requirement. Until 2015, all visitors paid a $25 exit tax at the airport prior to departure but this is now included in the costs of the flight.

It was common to meet doctors, engineers, scientists and other professionals working in restaurants or as taxicab drivers. However, in response to stricter economic sanctions by the US and because the authorities were pleased with Cuba's economic recovery, the Cuban government decided in October 2004 to remove US dollars from circulation. In its place, the convertible peso was created, which although not internationally traded, has a value pegged to the US dollar 1:1. A 10% surcharge is levied for cash conversions from US dollars to the convertible peso, which does not apply to other currencies, so it acts as an encouragement for tourists to bring currencies such as Euros, pounds sterling or Canadian dollars into Cuba. An increasing number of tourist zones accept Euros.
Title: Visa policy of Cuba
Content:  Visitors to Cuba must obtain a visa before travel or a tourist card from one of the Cuban diplomatic missions, travel agencies or authorized airlines unless they come from one of the visa exempt countries. All visitors, including those with Cuban nationality residing outside Cuba, must hold valid return tickets and proof of medical insurance. Non-Cuban passport holders must also provide proof of financial solvency of at least US$50 per day. Visitors from many countries are expected to hold a passport valid for at least two months from the arrival date.

The leaders of the government recognized that the new measure was unpopular but necessary to contain the flight of capital to other countries, such as Panama, where Cuban citizens traveled and imported items to resell on the island. On January 1st, 2021, the government launched the "Tarea Ordenamiento" (Ordering Task), which was previously announced on national television by President Miguel Díaz Canel and Gen. Raúl Castro, the then first secretary of the Cuban Communist Party. This is an effort, years in the making, to end 
Title: Cuban peso
Content:  Before 1857, Spanish and Spanish colonial reales circulated in Cuba. From 1857, banknotes were issued specifically for use on Cuba. These were denominated in pesos, with each peso worth 8 reales. From 1869, decimal notes were also issued denominated in centavos, with 100 centavos for each peso. In 1881, the peso was pegged to the US dollar at par. The currency continued to be issued only in paper form until 1915, when the first coins were issued. In 1960, the peso lost value after the United States imposed an embargo against Cuba and the suspended the sugar quota. Fidel Castro then introduced the socialist planned economy to Cuba with the Soviet Union

Every Cuban household has a ration book (known as libreta) entitling it to a monthly supply of food and other staples, which are provided at nominal cost. In 2016, the Miami Herald wrote, "... about 27 percent of Cubans earn under $50 per month; 34 percent earn the equivalent of $50 to $100 per month; and 20 percent earn $101 to $200. Twelve percent reported earning $201 to $500 a month; and 
Title: Cuban peso
Content:  The Cuban peso (in Spanish peso cubano, ISO 4217 code: CUP) also known as moneda nacional, is the official currency of Cuba. The Cuban peso historically circulated at par with the Spanish-American silver dollar from the 16th to 19th centuries, and then at par with the U.S. dollar from 1881 to 1959. The Castro regime then introduced the socialist planned economy and pegged the peso to the Soviet ruble. The Soviet Union's collapse in 1991 resulted in a Special Period of difficult economic adjustments for Cuba. From 1994 to 2020 the Cuban peso co-circulated with the Cuban convertible peso (ISO 4217 code "CUC"; colloquially called "kook" in contrast to the CUP or "koop"), which was convertible to and at fixed 
Title: Cuban passport
Content:  Cuban passports are issued to citizens of Cuba to facilitate international travel. They are valid for 6 years from the date of issuance, but have to be extended every 2 years. The cost of issue of this passport is about US$200 (CUC 200) and US$200 for every two years if one person lives in the United States. In addition a Cuban national must pay 200 Euros every two years if the person lives outside of Cuba in order to gain permission to enter Cuba. Without this permission and a Cuban passport a Cuban cannot enter the island and will be denied entry. Until 14 January 2013, the Cuban government required that all Cuban citizens and foreigners such as foreign students 
Title: Dollar store (Cuba)
Content:  In Cuba between 1993 and 2004, a dollar store was a government-owned shop that sold goods solely in exchange for hard currency, originally mainly to foreigners, in the same way as a Friendship store in the People's Republic of China or an Intershop in the German Democratic Republic. In 1993, Cuba made the United States dollar legal tender. The "dollar stores" accepted payment in US dollars and in Cuban convertible pesos. In November 2004, the US dollar ceased to be legal tender to use in cash commercial transactions and was replaced by the Cuban convertible peso. However, the "dollar stores" remained open and despite their acceptance of only the convertible peso, the term "dollar stores" remained in colloquial use. Starting in 2019, and greatly extended in 2020, a number of stores were converted with prices set in US dollars, and payment only by card - either special MLC cards issued by Cuban entities or international cards such as visa or mastercard.
