My current leave to remain to remain based on retirement expires on 22 April but I will be in Europe from the 7 to 24 April, I believe I can renew before I leave, say on or about 25 March, is that correct?

If the line for re-entry permits is too long on the day I go to CW can I get a multi re-entry permit at Suvarnabhumi?

Thanks in advance

It is not a leave to remain. It is an extension of stay based upon retirement.

You can do your extension application up to 45 days early at CW. You will be well within that if you go on the 25th of March.

You can get a re-entry permit on departure from the country 24 hours a day at Suv. They will do a multiple re-entry permit. The fee will be a total of 4000 baht because they charge 200 baht for dong the photo, copies and form for you.
