Do I need to leave Thailand every 90 days with a Multi Entry O Retirement Visa?

and we're done. Robert was gracious enough to provide

@Tr***

the answers she was seeking (despite not bothering to answer my questions :( )

Another mix of three total different things. You got an Extension of Stay based on being over 50 years of age (you call it a O Retirement Visa) and with this stamp you are allowed to stay 1 year inside Thailand. To travel you bought another stamp called the Re-Entry Permit, (you call it Multi Entry), with this stamp you get every time you come back into the county the same date as mentioned in the big stamp with the text Extension of Stay permitted up to ../../.. Now because you are allowed to be for 1 year inside Thailand, you must report than you are physically 90 days inside the country. You do not have to leave, but you have make these reports.

@Trudy ********

, how about you state WHERE you got the Non-O "retirment visa" and whether it is a 90 day single entry or a year long multiple entry.

My understanding is just get it extended in Thailand every 90 days
