Hi. I am writing this early to ease my mind and so we don't get jammed later. My Thai wife (married 4+ yrs.) and I flew from Canada to Thailand thru Hong Kong arriving Bkk with COEs on November 4th. My e-Visa is a 90 day, Non-Immigrant O, Single Entry, and the Visa conditions are: "Family of Thai National" My passport is stamped "Admitted on Nov. 4 Until Feb. 1 2022". We have a ticket to leave Thailand on April 1, 2022 to fly to London (family visit); from there we fly to Canada on April 25. So please and thank you, my questions are: (i) how do I extend/renew my Visa to stay here until we leave on April 1? (ii) if we can change our air tickets and decide to stay here in Thailand sometime between April 1 and April 25 what can we do? In both cases, we do not wish to actually leave Thailand to extend my Visa. We spend much of our time in Udon Thani at the family farm and on arrival earlier this month we filled out the TM30 at Udon Immigration with no issues. I do have 400 K Baht in an account here for over a year now. Please let me know what I should do. Many thanks.
