I have Non “O” 90 day retirement expiring on 5th May. Another stamp says see immigration for re-entry permit before leaving Thailand. I’m sailing from Pattaya to Indonesia on 22nd March & flying back to Bangkok from Singapore on 3rd April. Do I have to get re-entry permit before I leave Thailand or can I get Visa exempt on arrival & then still apply for my 1 year extension when I return? TIA
