I am not familiar with the Immigration laws of the UK. In the United States, it depends on how the person came to the country and how long they've been "illegal." If the person snuck across the border, s/he cannot get a greencard without first going home, even if s/he marries a US citizen. If s/he came on a visa but overstayed, then s/he can adjust status to get a greencard without leaving. If s/he has been in the United States illegaly for over a year, s/he will not be able to come back for 10 years once s/he leaves. The only way to overcome the 10 year bar is if a US citizen spouse or child can prove that the alien being barred for 10 years would cause extremely unusual hardship him/her (the citizen, not the alien.)
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.
It's not illegal.
No he cannot
Your status is "married." You are still a citizen of this country. There is no special status.
If you are married, you can apply for divorce.
no not unless they where married to a USA partner.
the US citizen shouldn't
=An immigrant is NOT an alien.==The immigrant would still be legal because they were married to a US citizen.=
Firstly, if the person is married in an another country and has come to a particular country illegally it is surely invalid to marry the person. Another thing, if the person is a citizen of that particular country in which he has married it is his right to first take a citizen of that country in which he is going to marry and then he can marry a person another to his own country.
You can be removed from any country that has a valid reason for the deportation. Esp if they have a warrant against them in a country just waiting to hear from them and NZ does not want them there.
I believe that you're guaranteed a citizenship when you marry a citizen, but being an illegal complicates the matter.
Yes they can apply - there will be tough questions though.
