Did it already in Canada, which was and still is a good fifteen years ahead of the US.
My Thai partner and I moved to Canada in 2000, me from the US, he from Thailand. We were admitted as a couple and got our citizenship three years later. We also got legally married. On th tenth anniversary if our legal marriage, in 2013, we celebrated by putting on a true wedding/recommitment ceremony for 45 friends, complete with ballet dancers and a very hot Scottish accordion player in kilts that even the straight men wanted to go home with. Our MCs were our two dearest friends (a straight couple) here in Vanciuver, and the bar man wore the hottest leather pants.
Happiness in marriage to a Thai man is possible, but you need luck and some hard work bridging cultural and age differences. It seems that, even now, every day I learn something new about how he thinks about the world. We met when I was 43 and he was 21. Now I'm 66 and he is 44, reading on the couch across from me in our condo living room. Marital bliss is not for everyone, but has worked for me. I'm very lucky. But some of you single guys seem lucky too, and I'm enjoying reading about your exploits and getting a vicarious thrill here and there.
