Yes, they can, but there are alot of legalities involved with "legalising" the person in question. It used to be a quick way to citizenship, but two of my friends went through this in about 2001 (her: American from Detroit, MI, him: Canadian, from Windsor, ON) and they gave both of them a whole lot of trouble. It should be easier with time, however. * In the U.S. unlawfully present foreign nationals are allowed to marry a citizen or other non citizen, if they have the documentation required by the state in which they wish to marry. Because of the changes in national security regulations an "undocumented foreign national of illegal status" would not be able to enter into a legal marriage to a U.S. citizen, as they would have to supply a photo ID, a birth certificate, and a Social Security card (not just a SS#).
It is legal in the United States for an illegal immigrant to marry a US citizen. Once the marriage is legal, the illegal immigrant becomes a legal immigrant and can stay in the US for the course of the marriage.
No he cannot
the US citizen shouldn't
no not unless they where married to a USA partner.
If you are married, you can apply for divorce.
Anyone born in the US, regardless of the citizenship of the parents, can elect to be a US citizen.
no
=An immigrant is NOT an alien.==The immigrant would still be legal because they were married to a US citizen.=
Yes. If the illegal immigrant marries a citizen, they can become a citizen from that.
No.
If an undocumented (illegal) immigrant is married to a U.S. citizen, then they are a U.S. citizen. So their divorce from another U.S. citizen won't affect the status of their child at all.
My guess is no. You have to prove that you have a real marriage to stay.
