I know their employer, and the strict standards that are used when screening applicants. MANY of them have become Americans.
Now, you may say, how can a person be labled a Cuban, if they live in America as a citizen?
It is no different than when my grandparents immigrated. They would say they were Canadian, but had become naturalized citizens and are now Americans.
Interesting. My grandparents all came from Poland and not one of them would ever tell you they were Polish. They all said they were Americans after the day they got their citizenship. I guess that's the difference between those that really believe in their American citzenship and those that see it as just an adjunct to themselves and their identity.
