Hey again knowledgeable ones. My wife is getting a non O here in Chiang Mai, and I'll be her dependent. We'd like not to both leave the country at the same time because of our kids.
1) Could I convert my tourist visa to non O- dependent visa at Chiang Mai immigration?
or
2) Could I apply for the non O dependent in Vientiane if I have all the documents (proof of marriage, letter from employer, etc...)?
