QUESTION: Where can I obtain statistics about illegal immigrants from Cuba?

How many Cubans were deported as illegal immigrants last year? As you may know, the government distinguishes between Cubans who land in the U.S. (who are given immediate preferential immigration status) and those intercepted in international waters (who are sent back to Cuba as "illegals").

I ask because in arguments for the "wall" along the Mexican border, supporters raise the question of the number of "illegal immigrants from states which support terrorism" who have been intercepted along the southern border. Since the U.S.government considers Cuba to be such a state, it would be useful to know how many of those "illegal immigrants" were Cubans as opposed to, say, Iranians or North Koreans.
