I have a flight departing at 9:00 AM from Suvarnabhumi Airport to the UK. I am worried that the Re-Entry Permit Issuing Authority will not be open prior to my departure time at the Airport.

How long does it take to process a Re-Entry Permit Application prior to Boarding Time?

What do you reckon?

Thanks in advance/

It's open 24/7. Allow at least half an hour, normally it takes only 10-15 min.

George is a frequent traveler and has no fear of doing at the airport. I tend to worry if things are not done in advance and recommend doing at an immigration office when you are not under the stress of flight and can remember your own name.
