this depends on the Immigration . . . . . his Immigration would have suggested it, if it was possible, however they didn't and put his application into "fast track" mode instead
You should have done everything by the book. It is a well known fact that when a 1-year Extension of stay permit is issued with the reason "married to a Thai wife", the extension will always be issued for "4 weeks under consideration", during which period Immigration is going to do a home visit, and they expect YOU and the WIFEY to be present! They will ask your neighbours if you really live together and if your marriage is real. Then after the under consideration period you can pick up the stamp for the rest of the 1-year extension. You are NOT supposed to do any travelling until you have been issued the full stamp, and you are not supposed to buy any re-entry permit, because ist cannot and would not be sold for just the 4-weeks of consideration period by any Immigration just because it is NOT part of the procedure . . . . the re-entry permit can however be had for the full extent of the 12-months extension - once you got it definitely issued!
Larry Johnson . . whichever way you chose, be aware that for applying to the 90-days Non-O visa inside Thailand you need a Thai bank account with 400,000 THB sitting in it. For applying to the 90-days Non-O visa in Canada, you can use income or money in the bank. . . .and for ANYTHING you apply on Immigration, you need a "Kor Ror 22" a marriage registry document that shows your marriage is registered inside Thailand. If your marrriage is only registered in Canada, you need to have it acknowledged in Thailand, first thing, before anything
when you enter, you get stamped in for a 90-days stay permit. The Non-O Visa will become invalid. Then before this stay permit expires, you apply for the 1-year extension of the stay permit (based on reason retirement). The 1-year extended stay permit will begin on the day AFTER your initial 90-days stay permit expires
that's when AI is complete and utter nonsense. FIRST: he doesn't have any visa, he has a "stay permit" and this stay permit got a number - which is handwritten into the upper left corner. If ANY, then this number would be the correct one. However the field "visa number" is not mandatory, so he can leave it empty. The number you gave him is the number of the single re-entry permit !
