I am in a bit of a quagmire on how to get my filipina gf a tourist visa to USA to visit my parents. They are retirees and not fit to travel over 24 hours flight to meet her. I would like for them to meet her before we get engaged. It would feel weird otherwise. We are both qualified teachers in Thailand. We don't want to live in the US, just visit and meet my parents. We are hoping to marry in the USA (on holiday), but it is not necessary. It takes us 7 months on avg to get an embassy interview just to be turned down. I actually have plenty of other coworkers that are in the same predicaments with their husbands, wives, and fiances. The visa officer says my gf doesn't prove she will leave the USA. We don't have assets in Thailand since neither of us are citizens there. We just have money in bank accounts.
Does anyone have a recommendation how we can get the tourist visa?
Plan B is getting a fiance visa. Would it be ok if I file this from Thailand, then we travel to and marry in USA and return to Thailand?
Option C, which is inconvenient, is she gets a teaching visa to usa. Filipinas can get those since USA has teacher shortages, but then we need to live and work in the USA, which we don't want to do.
I would appreciate constructive help. The whole goal is for her to visit the USA and meet my parents. It would be a blessing if they live past 5 years, so speed is a bit important.
