Sorry if this has already been asked.
I have a UK passport, a non-B visa and a multiple reentry permit.
I left the country recently through BKK airport and noticed I was able to pass through immigration using the new e-gates. I wouldn’t get an exit stamp using these gates. I asked a staff member if that was ok to not get a stamp, as I have a visa and re-entry. She didn’t know so I queued up in the normal queue instead and got stamped out.
Can I use the e-gates next time?
