I said I would update about the re entry counter at Suvarnabhumi airport.
I’m here now Friday 10 April it looks closed but it’s not and still says open 24 hours but no one at desk they called a lady to help me.
It was very quick 5 minutes, I got my multiple re -entry permit on my Non Imm multiple entry visa issued UK.
I would like to thank everyone who helped me on this site,and echo the thanks to all the immigration staff staying in post at the airport very brave of them.
