Can an illegal US immigrant get married to a Swiss citizen in Las Vegas?

Current residence and home residence matter very very little. What matters is honesty about it. Marry him where he and you will, As long as the Swiss government recognizes the validity. As you say, his passport IS valid. So, his home of origin is already on it. Current residency should also be truthful. Whether he is a legal US resident matters little, That's would be left between the US and your new spouse. The Swiss will not care. Because they care that you and he obey their laws. US law is as minor a point on Visa's and residency, for the Swiss--or any other Nation, as admitting he bought a pack of cigarettes for a minor in Vegas. He did not do it in their nation.

Good Luck, Be Happy..

Borel, he's not a criminal, he was taken by his family to the USA when he was only four years old. Basically, he has to pay the price for it now. He wants to leave the US at all costs because he has no future there as an illegal immigrant. I have talked to a Swiss lawyer (who wasn't specialized on immigration/marriages though), and he recommended getting married in Las Vegas because he can't apply for a marriage visa that he would need to come marry me in Switzerland. He has also applied for the Deferred Act and should have that by the time we're getting married.

If he has a valid passport, you guys can get married, sure, pretty much anywhere except in Maryland which requires a valid SSN when issuing a marriage license. In all other states filling in 000-00-0000 is all it takes. Many thousands of visitors get married every year in the United States.

The problem will be Switzerland, as the Swiss consulate in the United States will NOT issue him a visa without proof of lawful residence, so he'd have to travel to his home country for that anyway.

That being said, would you please listen to yourself? You have been "dating your boyfriend online for 2 years?" Is that like online sex where you masturbate in front of a computer screen? Your boyfriend is the guy you go out with, often live with, not a guy from the other side of the computer screen. I have no idea how young you are, but telling us that you want to marry a guy you don't know anything about is just as immature as it gets. He can have horrible breath, fart all night, is into kinky anal sex with a goat present . . . no way of knowing any of this. Grow up, kid.

Due to his record of immigration law violations in the US, he is inadmissible to Switzerland (& most countries around the world). He chose, as an adult, to continue violating visa regulations & immigration laws when he stayed as of his 18th birthday. What his parents did when he was a child is irrelevant!

He had his chance to make things right, and he blew that off, and chose as an adult to break the law. If he had returned to his own country before his 18th birthday, he would not have been penalized for his parents' illegal acts. But on his 18th birthday, he became solely responsible for his actions.

If you proceed to marry him, he will have to return to his country of citizenship, then apply for your immigration there. Switzerland (and most other countries) will not admit him due to his record of HIS lawbreaking.

DACA is not relevant here. That does not change his status as an illegal alien. It only delays or defers his deportation for up to 2 years. He is scheduled for deportation as of date of expiration of his DACA temporary permit.

the chances of Switzerland taking in an illegal criminal is pretty much zero... of course aiding and abetting him is a felony in the US.

you would need to talk to a Swiss immigration lawyer before doing anything
