Why do you ignorants even post since you know nothing? Marisa, to marry you in the US your fiance can be on ANY kind of visa or even WITHOUT one
Why ignorants like you even post anything? Sure he can marry on a tourist visa and when he leaves the country he won't be able to come back to the US for at least ten years because he defrauded the US gov. and didn't change his status to a conditional green card resident. Same if he come on a K1, B1 or any other kind of visa, even if it did expire what is the purpose to marry in the US if you don't follow up with the proper procedures. You will just have a marriage certificate issued in the US but he will not be a resident and if you ever want a divorce he is not a US citizen and the US will not grant a divorce to a person who can't stand trial in the US.
Grubas you are a prime example how to illegally defraud the US gov. by telling others to do so.
