I am still on non OA. The plan is she gets the non O, then I apply for the non O as a trailing spouse.
This brings up my other question. Our marriage certificate was issued in Canada, instead of going back to Canada, can we get a Canadian law firm in Thailand or overseas (eg HK) to notarise it? Is it accepted by overseas Thai embassy/consulate when I apply for it?
No need to go back to your home country for the extension. Just go to the Immigration Office where you live. The current insurance requirement is 3M Baht inpatient.
That depends on how many times you will leave and back during the extended year. If you foresee it will be quite often (say more than 3 times), it’s still better to get a multiple re-entry permit. If not that many times, u can get a single re-entry permit every time before you leave the kingdom.
Which means I can skip the first year’s extension and by the time the 2nd year’s stay is coming to end, I can still do the extension, provided that I meet all the requirements?
