Was told today more or less the same in Nakhon Sawan except Covid extensions have stopped and only giving 30 days only that have to be approved by Chang Mai so everything submitted in double and starts the day you apply not when your extension finishes. Then it's off you go.
I need a non O but can't apply inside the country unless I'm on a tourist visa or 30 day. All my money is in Thailand so can't show funds in UK bank. It's a pain.
