Thought of this when watching the movie Maria Full of Grace last night (good movie):
I don’t recall when I left the US for overseas (in early 1990s) a very rigorous checkpoint system. Seems like this would be another ideal time to catch people who came illegally. Granted, maybe a bit harder since they may not be smuggling. But still, seems likely people who came in and over stayed or what not, or who walked in the country and now have fake papers, could be caught. Are there checkpoints when leaving the country? I just recall getting on the plane with everybody else like we leaving for Iowa. My memory might fail me, as I recall the hassle of coming into Miami from overseas better.
