You can get in immediately, if you just fly to Mexico and walk over😂
A U.S. B2 VISA (Tourist) can take a few days from Aplication (On-line) to the Interview (Just the wife at the Embassy) to the VISA in the Thai Passport.
The unknown variable is the VISA Interview Appointment. The interview itself takes 5 min if Married (legally).
My wife did her B2 VISA (PROCESS) in a week and had her passport back with B2 VISA stamp in another week.
However, our son’s took a month from start to finish, because we had to wait about 3 weeks for an Interview.
The bribes are a big issue. When I did it myself, a bribe was expected. It was awkward for me, but I got the message. It cost me 3k bht. I was held hostage after an 8hr process.
Such happens, and always beyond one’s imagination. It is a Charecter that makes Thailand unique. Those who understand and can move on about letting life happen, find peace here.
Yes, of course. If you do not, one is already planned for you. I recommend a resourceful place that has the resources to plan and execute. This happened to me a year after I redid my Non-O, by which latter in that year the Immigration Officer was convicted, and they further invalidated all her approvals and I then had a 1 year overstay. Fortunately, my spouse is a Misisteri staff member and worked everything out. However, as part of the following years Non-O, I had to leave the country and re-enter from my home country after I personally picked up paperwork from the Thai Embassy and fly within 72 hrs. Plan for the worst.
