Good luck. Embassy can deny tourist visas if you doing them back to back as a way to live there. Your best bet is to travel to nearby country for a few weeks and fly back for another exemption. Multiple back to back exemptions will also get you questioned and possibly denied entry

What reason did you pick for the transfer?

@Debbie *******

the embassy in Cambodia or Lao probably will not give you back to back tourist visas. You best best is a border bounce for 30 days and then extend once for 30 more. After that fly to another country for a week and then come back. After you've fill a few pages of you passport with back to back entry stamps they may question you on why. It would be helpful to have a phone number of a Thai girlfriend to let them know why

Find a pain doctor to give you cortisone shots

If going on wife visa, she will need to pass the background test, and embassy interview. It will take you 2 years of, waiting to get her a visa and green card. Your best bet is fiance visa, which will take a year after above checks
