yes, we are having issues because she doesn't have a Thai ID and we can't find our original marriage certificate so I think we will bring her on the tourist visa and get the Thai ID once here
I have emailed the Thai Consulate in LA, but now I'm thinking maybe easier to just apply for 3 90 day e-visas (me, my mom, and my daughter) and just sort my daughters ID out once in Thailand. My wife has a valid Thai passport, so she isn't an issue.
