marry her here, then you don't have to get your US marriage license translated, and you can also get a type O extension based on marriage. Also, the wait period in either case can be over a year for her to get a visa to the US. It is not automatic. It is very involved just getting to the interview stage for her, and even being married it is never a guarantee she will get a visa to the US. The US recognizes legal Thai marriages, so you don't have to get married again. What some people do is get married here then at the same time they apply for her visa to the US they also apply for her Green Card here. It takes longer, but then in the future she doesn't have to go through the hassle of the US visa process, but, she can still be turned down.
