Hello I am thinking of making a non-immigrant visa 0 in order to go to Thailand but I want to stay there for about 5 months this visa is it easily extendable and if so for how many days thank you very much

Hi all, just to confirm what I’ve researched, my options for entering TH soon for the short term are 1) visa waiver on arrival for 45 days (15 ASQ) then one time extension for 30 days or 2) SETV for 60 days (15 ASQ) then one time extension for 30 days? Then consider other options for staying longer once there?

Then my decision is simply whether or not the SETV is worth the cost, admin and processing time for the extra 15 days?

TIA 🙏
