Good morning, I am (UK55) moving to Cambodia in November. I am travelling to Cambodia tomorrow for a few days, if I return without a reentry permit will I just get 45 days on arrival, and my O visa (based on "retirement") be cancelled?
If I don't plan on returning before my O-visa expires (Dec) is there any advantage to be gained by getting the reentry permit?
TLDR : Answer Summary
If you leave Thailand without a re-entry permit, your current O visa's extension of stay will end. Upon re-entering Thailand, you'll receive a 45-day visa-exempt entry. If you don't plan on returning before your visa expires, there is no advantage to obtaining a re-entry permit.
