You don't need Thailand Pass if you are staying "airside" and not going through immigration.

Is it on one ticket with checked through baggage?

@Ginna ******

Absolutely not.

It's not just a transfer. They are in PPE, etc. It's not a taxi.

@Darcy ******

You're asking immigration about an extension when you still have a valid visa. If your visa is still valid then you can leave and re-enter and get another year. You'll need to meet the entry requirements but the financials were required to get the visa and you don't need to do anything about them now. You'll need insurance like you did last time you entered.

If you leave and re-enter before the visa expires you'll be stamped in for another year. You'll need a re-entry permit to leave during the second year.

The visa lasts a year and you're stamped in for a year on arrival. Any time in visa validity year.

@Glenn *******

Just follow your embassy/consulate rules

No they don't need to be notarised. Who said they should be?
