Am I eligible for another COVID extension while in Thailand on a 45-day visa exemption?

only people on visas on arrival (which you do NOT have) and Non-Immgrant type visas/extensions are prohibited from applying for a covid extension during this new program that runs until March 25th. So you are totally able to apply for another one (y)

Now could it be more problematic getting the extension? Certainly could be and they could require proof you're leaving in another 2 months or they might not even ask. It's just a crap shoot really. 😕

I would definitely have a plan B in case you are denied another 60 day covid extension when you go apply and are given a 7 days get outta dodge stamp instead 😮 .

You are eligible as you entered visa exempt. However it’s up to the immigration officer to grant one. That being said no reports of them not being granted (except to VOA and non immigrant visa entries ) although they’re seemingly making it tougher to get.
