All advise are correct. Problem is you can't log on their app for applying and renewal. I got all including Dr paper since end April no go, nobody knows when here in chatuchak.
Tod Daniels, thank you for the info. This year I chose not to get a multiple just my yearly "O"as we don't know if we can travel saving few bucks. Never done this before, If I am departing do I get and pay re-entry permit stamp prior to immigration inspection or after immigration? Does re-entry stamp have a time limit or just based on the visa year end date? Also, upon return, is it required to stop by the re-entry again and pay or just one time "outbound" only. Thank you for great advise and reply. Cheers
