Under the previous policy, Cubans who made it to dry land in US territory were permitted to enter the country and take advantage of the 1966 Cuban Adjustment Act, which allowed Cubans to claim permanent US residency after one year in the country. Cubans who were interdicted at sea by the US Coast Guard, on the other hand, were returned to Cuba.
[...] On January 12, President Barack Obama announced that, effective immediately, the US government would end the so-called "Wet Foot, Dry Foot" policy, as well as the Cuban Medical Professional Parole Program. In a joint statement detailing the changes in migration policy, the Cuban government agreed to accept Cuban nationals deported or returned by the US.
Through these programs, Cubans were extended preferential immigration status and a continued incentive to leave the country, which contributed to a "brain drain" of trained professionals and provided Washington and right-wing Cuban exiles the fodder for propaganda about state repression in Cuba fueling a constant stream of refugees.
Cuba has an abundance of well-trained medical personnel. Economist Dean Baker has pointed out that allowing the American Medical Association to construct artificial barriers to expanding USA's medical labor force is dumb and makes healthcare more expensive.
In an overhaul of one of his predecessor's signature legacies, President Donald Trump will redraw U.S. policy toward Cuba on Friday, tightening travel restrictions for Americans that had been loosened under President Barack Obama and banning U.S. business transactions with Cuba's vast military conglomerate.
Trump's changes are intended to sharply curtail cash flow to the Cuban government and pressure its communist leaders to let the island's fledgling private sector grow. Diplomatic relations reestablished by Obama, including reopened embassies in Washington and Havana, will remain. Travel and money sent by Cuban Americans will be unaffected, but Americans will be unable to spend money in state-run hotels or restaurants tied to the military, a significant prohibition.
