Sorry for my delay in responding Ubon Joe. Ok, so, my visa was stamped by Suvarnabhumi imm. official upon my initial arrival in Thailand Nov 1, 2021 as: "TR Multiple 60" dated Nov 1, '21 and valid to 30 Dec '21". In the US, I applied for a special (as opposed to the normal 60 day tourist visa) 2nd option Tourist visa called "Multiple" for a 3 x 60 = 180 days - it costs double in price to the ordinary one). I had to submit all my flight details (arrival date and final departure back to US date at time of application). This confirms that some countries do, indeed, issue these, as you wrote. When I went to immigration end of Dec here in Thailand to get my Covid extension I was stamped "extension of stay permitted up to Feb 29, 2022". I assumed that this meant I can either depart the country by that date (and re-enter for my final leg of the visa), or, apply for another Covid extension that would give me another (my final) 60 days. I plan to return to US 20 April. I hope that I am offering a bit more background to my issue. My question is: can I simply leave the country eg. a short 5-7 day trip and come back in with additional allowance give for my stay until 20 April, or can I choose to do another Covid extension and if so, will I get 30 days or 60 days granted at that time? Needless to say, a visit back to the immigration office seems imperative.
