I left the country 1 month after 90 day reporting (october). Got back another rmonth later.
Now my another 90 day reporting based on the slip I got initially should be done this month, (january), however I read that once you left the country it resets.
I didn’t get any new slip whatsoever at the airport with a new date for reporting.
Should I count the days myself or just go to imm based on the old slip and request a new one?
TLDR : Answer Summary
Upon reentering Thailand after leaving the country, the 90-day reporting requirement resets. You should count the days yourself starting from the day you arrived back in Thailand, which is considered day one. It's advisable to visit an immigration office to obtain a new reporting slip instead of relying solely on the old slip from your previous stay.
