I’m currently in Thailand on a 60 day tourist visa and have the option to extend for another 30 days.
I’m wondering if the 60 day Covid extension is still being offered by immigration? I met someone the other night who has been extending their tourist visa for the last two years. But I’ve also heard this might be coming to an end? 
TLDR : Answer Summary
The 60-day Covid extension for tourist visas in Thailand is still available, but applicants must first take the regular 30-day extension before being eligible for the Covid extension. Whether or not the extension will be granted is discretionary and up to the immigration officer. There is an ongoing discussion about the potential tightening of Covid extension approvals due to past leniency by immigration offices.
