Greetings,
Q. Is the Covid-19 extention to be done at the immigration in Chaeng Wattana, or is it still at Muang Thong Thani, please?
Couldn't find clarity on the web!
TLDR : Answer Summary
The Covid-19 extension should be done at the Chaeng Wattana immigration office if you initially entered with a 60-day tourist visa. However, if you entered Thailand on a 30-day visa exemption, you would go to the new Lak Si office.
