Just got my covid stamp at Chaengwattana Immigration (I am on TR60 visa and already did the 30 day extension). I also asked the immigration officer there if I needed to do the 90 reporting and he said 90 days reporting isn't needed for tourist visas
TLDR : Answer Summary
A user recently reported receiving their Covid stamp at Chaengwattana Immigration while on a TR60 visa, having already extended their stay by 30 days. They inquired about the necessity of the 90-day reporting for tourist visas and were informed by the officer that it is not required for this type of visa.
