Under the Cuban Adjustment Act, a law Congress passed in 1966 in the early years of enmity with Fidel Castro, any Cuban who sets foot on American soil is given permission to enter, known as parole. Cubans are also eligible for federal welfare benefits including financial assistance for nine months under separate policies from the 1980s. After a year, they can apply for permanent residency, a gateway to citizenship.
The recent exodus from Cuba began in mid-2014, even before President Obama in December of that year announced a restoration of diplomatic relations with the government, now led by Mr. Castro's brother Raul. In a major change, President Raul Castro allowed Cubans to leave the country without exit visas. Many Cubans have said that rumors that the special entry to the United States would be canceled had caused them to pack up and go.
"The rumors are unfounded," Alan Bersin, assistant secretary of Homeland Security, said in an interview, seeking to dispel the fears. "The Cuban Adjustment Act is still in effect and is part of the overall immigration policy and there is no intent presently to change that."..........
