It's possible to do so, yes. You should check with customs and immigration before leaving the country to identify any potential problems... it's a lot easier to get them straightened out when you're still in the country rather than when you're stuck in an airport (or something) trying to reenter the country.
your a weirdo
If you are a US citizen and marry an illegal alien who entered the country with a valid VISA, he would not have to leave the country. You would have to have his status adjusted so he would no longer be in the US illegally, however.
no they have to go through the process in the Us.
I would see a lawyer. I am sure there is a way.
If you marry someone from another country, they are no longer illegal, but a resident alien. The above response does not answer the question. If you marry an illegal person in the U.S. it is not that simple. The government may require that person to leave the county up to 3 years.
No, an alien or immigrant, legal or otherwise, does not become a citizen automatically upon marriage to a citizen. There is a process of applying, processing and (hopefully) eventual approval by the Federal government. First is Permanent Residency status ("Green card"). Then there's a wait of 3 years or more - depending on situation - for citizenship qualification. The website for the agency which handles this process is: USCIS.GOV An illegal alien does not automatically become a citizen by marrying one. However, certain illegal aliens can get permanent residence status (often called the "green card") by marrying a US citizen. If the person originally entered the United States legally but overstayed his or her visa, than it is possible for him or her to "adjust status" to that of a permanent resident (i.e. get a "green card") if the US citizen fills out a series of petitions including one that proves that the US citizen can financially support the alien. If the alien entered illegally into the United States without any visa or permit, than that person cannot "adjust status" and has to leave the country before obtaining a green card. If the person was illegally in the country for more than a year, than he or she is barred from ever coming back for 10 years (known as the "10-year-bar") The only way to overcome having the 10-year-bar is by the US citizen spouse filing a petition for a waiver of the bar. The petition has to prove that it would cause extreme and exceptional hardship to him or her to move to his or her spouse's country. Only three years after the person has the green card can they apply for citizenship, and they must still be married to the original citizen who got the green card.
No you do not have to leave your religion after marrying a guy, you can keep your religion and he can keep his.
Your best option would be to leave the country, apply for a marriage visa, re-enter legally on the marriage visa and then get married.
The simple answer is, NO, at least not right away. An illegal alien gains very little from marriage to a permanent resident. You cannot adjust status to permanent resident inside the U.S. You would have to leave the country to apply for an immigrant visa based upon the marriage.
Although there are not laws prohibiting a foreign national who is unlawfully present in the U.S. from marrying a U.S. citizen such an act does not change the non-citizen's illegal status. The citizen spouse cannot apply for permanent residency for the foreign national spouse, this means the non-citizen spouse is required to leave the U.S. and then apply for reentry on the basis of the marriage and according to USCIS regulations.
