The Consulate of the country you are from, located in the UK, probably can answer this question for you.
YES!
No. They're the citizen, not you.
he will stay American citizen....he has to apply to become a Canadian citizen or his wife has to apply for him and will have to tell the court that she has married him
my advice is he should because if he is married to a legal citizen he should get the same rights.
depends on where she was a citizen.
That gives you the right to stay in this country, but you are not a U.S. citizen.
No, sadly they will be sent back.
It depends. If you are a woman, no, you have to usually take the child back to America or wherever you came from. If you are a man, you have to stay with the woman to help support the baby.
If you came to the US and had a child you can be deported, however, they can not deport the child since he was born in the US and is a US citizen because of that. If however you married you can get a green card allowing you to stay in this country. However, you can try taking the citizenship test allowing you to stay in the country.
yes if you stay they will send you back
Yes, you may. It is both legal and popular.
if he entered illegally, unfortunatly the awnser is no
