Hello. We were originally on a non-immigrant visa then had to convert to a COVID visa which will expire on 8 Aug, Sunday. Our flight out of Thailand is on 7 August, Saturday. So my questions are, in case our flight gets cancelled on the last minute, do we get a penalty for overstay if we renew on 9 August, Monday? Or best to renew our visas on 6 August, Friday, just to be on the safe side?

We process our visas in Samut Prakarn immigration office.

Thank you.
