Given 90 Days On Entry Without A Visa

[KunMatt]

I'm British. My Non Imm O visa expired a month ago while i was out of Thailand. When I returned to BKK and expected to be given a 30 entry stamp I saw that my stamp says I can stay for 90 days from the date I arrived.

Incidentally, a couple of years ago I had the opposite problem of what recently happened.

So what's the deal? Have the rules changed? Is this a mistake or is there some clause on a non O I am not aware of?

If it turns out to be a mistake on behalf on the immigration officer, because my stamp says I can stay 90 days can I legally stay 90 days in Thailand now? It would save me a hell of a lot of grief with getting a visa in Vientiane like I had planned!

If your visa had expired prior to entry the 90 day is in error and you will be overstay after 30 days if they find (as that seems to be all you would qualify for). Did they actually write non-o- on the entry stamp?

My Non O expired while I was not in Thailand on the 21 Dec 2011. I flew to BKK on 21 Jan 2012 and the stamp says admitted until 19 Apr 2012.

He's written "V" where it says "Visa Class" on the stamp.

Believe they will normally write non-o so suspect the 90 day stamp used was wrong in that case and that it will be detected on exit. Best to visit immigration to change before overstay.
