Can a US citizen marry a person who is on Tourist visa in US?

If you want to do it properly, here is how is goes. You and your betrothed need to visit a US Citizenship and Immigration Services (visit www.uscis.gov for more information) office to apply for a K-1 Fiance visa. Once your fiance receives the K-1 visa, then they need to leave the US (go to Canada or Mexico) and come back. Upon entering the US, the visa is activated and you now have 90 days to get married. Once you are married, then you apply for a family-based immigration for your spouse. While this adjustment of status (AOS) is going on, your spouse may remain in the US. In fact your spouse must remain in the US during the AOS. In order for your spouse to leave the US during the AOS, you must apply for and be granted Advanced Parole to leave and return. Once the AOS is complete, your new spouse will be a Lawful Permanent Resident (LPR) and well on the way to US citizenship. Good Luck.

Okay, I have said to others many times you have to make sure the guy'd like to marry the girl is not only for Green Card otherwise the girl would be stuck for the long of the married. And it's really bad and totally against the law if the immigration find out the girl might get in trouble as well. That's my warning. If he's true and love the girl like what he said, start right now gathering all the pictures and the the proposal's time when he bent his knee to ask the girl to marry him so you could put it on the paper work. If he came legally, he'd not be in trouble. They would approve his paper work within a year sometime it's faster. Some people they do the paper work themselves and some hire a lawyer. It depends on you. Let the guy do the paper work by himself and see how much he's needed. And tell the guy to love the girl more than ever because she changes his life. And welcome to America. You guys have to appreciate each other. you guys would be okay. Again ask around and hopefully you guys are happy married for each other.

Sure - there may be some red tape but generally it's not a problem. I have some friends who married some Irish who came here and it was not problem. More I think about - the more I think it's easily done. Think of all the US citizens who wanted to get married overseas - you see it all the time of shows - "the couple wants to get married in the Italian church where the brides great grandmother was married" or "this couple wanted to get married in a small church in rural Ireland". All you have to do is be able to time everything correctly.

I think the real issue is immigration. What does the non-US citizen have to do to stay in the country. I'm guessing the marriage partner would "sponsor" the spouse or something like that - but I have no doubt it can be done, it's done all the time.

Sure. The US citizen can marry whoever s/he wants as long as neither party is already married to someone else. There are no restrictions on that - but there are restrictions on people staying after their visa expires. The immigrant spouse may have to return to his or her homeland and go through the proper immigration procedures before being allowed to rejoin their mate. Check with the immigration department to find out exactly what the requirements are.

An American can pretty much marry anyone. However, if you'd like this person to stay here with you, you'll need to file an I-130 immigrant visa petition for your spouse, plus an I-485 adjustment of status form, and an employment authorization request and some other odds and ends. If you file everything you're supposed to, you spouse won't have to leave. In fact, your spouse won't be able to leave until it's all complete and adjudicated, unless they get Advance Parole from USCIS first. Check out uscis.gov for more information and forms.

In my understanding, yes, but the person who is not a citizen will need to apply for U.S. Permanent Residence, (assuming you will live here in the states). Then, if they choose, after 5 years they can apply for citizenship.

Call the US Department of State for more info.

yes, the USC can marry the person on tourist visa but it may be deemed fraud if the marriage is done close to the person's (tourist) entry date to the US.

the person on tourist visa can go back to his/her home country and the USC can file for a spousal visa so he/she can enter the US legally

if the new spouse chooses to apply for permanent residency (green card) then the hasty marriage will be very closely scrutinised. If CIS thinks its a fraud, then the green card will be denied and the spouse deported and the american possibly jailed for being an accomplice.

U didn'tsay whet country your intended to hook up with???

I'm pretty sure they can.
