Me again....
I have at present a METV from UK that states on the Visa it’s valid until 5th May 2019. My latest stamp says I’m admitted until 11th April 2019. I am visiting VietNam on 8th April for 1 week therefore able to extend my visa until I return to UK.
Question: other than passport is there anything I need for passport control at Suvarnabhumi or VietNam (like passport photo, show of money etc) thank you 🙏
TLDR : Answer Summary
The user inquired about requirements for passport control at Suvarnabhumi Airport and in Vietnam while traveling with a Multiple Entry Tourist Visa (METV) from the UK. The response highlighted that upon returning to Thailand, they should be prepared to show 20,000 THB or equivalent for entry, along with proof of onward travel and accommodation. It also mentioned that requirements for Vietnam are not related to Thai visa issues.
