I am in Thailand with extension of stay granted in December 2018 (extension of F-visa) at which time I got a multi re-entry permit.
I have now renewed my passport due to name change after marriage, but have been told that I can't transfer my multi re-entry permit, only my extension. I would need to buy another re-entry permit. Is this correct?
If so, can I travel in/out of Thailand with both passports until my next extension is due?
Many Thanks in advance of your advice.
