I’d like to see a refundable sponsorship visa, say $10K. I wanted to being my Thai GF to the US but she was denied visas multiple, even after we married. I’d gladly put $10K to have her visit the USA, refundable upon her US exit.
Wish it would work out for you both.
I highly recommend you find a good immigration attorney in your area. My wife is from China and I was able to get her permanent residency within a couple of years. I looked over the process very carefully and decided that I didn’t want to tackle that massive hurdle by myself. It cost about $&k but it was money well spent.
If you want to get some advice on our experience, Freep mail me.
