LoL, beat me to it Log. I suppose we should send back all those Vietnamese, Chinese, Korean, Iranian and Iraqi refugees from our previous conflicts, too. Clearly some information about asylum status is in order.
There was a tradition, at least at times in our history, when immigrants were welcomed. Remember the old "melting pot"? The whole "illegal immigrant" schtick is about misdirection (deliberate or not). "They" are "illegal" because our immigration system is so messed up it takes too much time and money to go through proper channels to get here legally.
I have a relative who just married a foreign national. She has traveled here several times, first on a student visa, then on a work visa (she is a journalist). Now, because she has married a US citizen, she has to be unemployed to show she is not here to work, but instead he has to show he has enough assets to support her even though she is perfectly capable of working, but now she can't because she has the wrong kind of visa. Work your way through that.
