that's where you're wrong. if it was purely tourist-based, then you wouldn't be getting married, you'd be travelling around.
if you're gonna marry, you HAVE to apply to a k1 one or you'll very likely have problems afterwards.
Wow. So it doesn't matter that the US govt itself says that there's no problem with getting married on a tourist visa, immigration lawyer says it doesn't matter, both as long as you don't try to get a change of status while your there and leave on time?
THERE IS NO PROBLEM WITH DOING THIS.
People, do a little research and quit assuming you know the answer on this because it "seems" like going to the States to get married, when NOT intent on changing status to remain in the States, is in any way illegal, fraudulent or in any way against what the US wants.
Who's to say that they are not going to do tourist things while they are there in addition to getting married? Who's to say you have to travel around to be a tourist?
As I mentioned before, the US government doesn't care one whit if you get married in the US while on a tourist visa. The entire issue is your intent on IMMIGRATION. A tourist visa is a non-immigrant visa and as long as you leave the country on time, and don't try to change status whil there, you can do anyhting in the US that it is legal to do.
Even if you DID change status, there are a number of opinions (from immigration lawyers - not in general) that if you o it between 30 and 60 days AFTER arriving on a tourist visa, you can even do that. The 30/60 day rule is a "go by" that is actually used for something else but many immigration officials will use that when reviewing a case of marriage while on a tourist visa for those who DO file for a change of status while they're there. Admittedly, this is a bit of a gray area and the only situation where there could be a problem with getting married int he US with a tourist visa.
