I got married 2 months ago in Chaiyaphum and it took 1 hour, no police check, nothing. Only thing needed was the translated/certified affidavit (paper saying that I can get married). The mayor will ask a few questions and that's it, you get your marriage certificate.
It will extend until the country fully re-open, which include 30 min out-in border run. I've said this since day 1, as long as people can't border run, Covid extension will remains.
Yep, as I predicted, as long as it's not possible to border bounce easily (go to Savannakhet, for example and come back 30 min later), they will keep extending Covid extension.
Thai Visa Centre is the owner of the group you are currently asking your question from. You can see their name on the banner above. Yes, they are legit. If it's "Center" with the wrong spelling, then probably a scam.
