Hi there, apparently my immigration officer stamped me in on my active type-O instead of the new type B visa ...despite me asking him to do so and explaining my situation (i had been approved for type B online). Is it correct that i now have to do a re-entry? How can i make sure on my next re-entry that this does not happen again?

Sounds like you had an extension of stay with a re-entry permit that was still active, which was why they stamped you in on that.. you printed the approved non-b PDF they emailed you and handed it along with your passport to the officer when you stamped into the country? There's no way to activate that nonb visa if you are already inside Thailand. You will have to exit and reenter

You should not really have applied for another visa while holding an active visa. Try and find a way to cancel that active Non-O or the same thing could just happen again.

First thing to try is to return to the immigration office that stamped you in. Ask them to correct it. If they do that, you’re gold. If that don’t, little lost and you try the reentry.

there's no harm going to the airport and seeing if they'll correct the stamp but PRINT out that PDF so it's a paper and not just on your phone..

just fyi I printed it this time and explained my case strongly. after some confusion they pulled me aside to sort me out. I was sure things must be going well too see this level of attention being given to me case , so I was shocked to see that the stamp was still on the type O extension's end date.

I insisted that I gave them a paper for a reason! Why would they ignore the typeB visa in their hands again! The officer insinuated i was crazy for choosing the 90days from a single entry visa over the O extension I already had. I explained that the MOE's OPEC insisted I use a type B, otherwise they wouldn't issue me a work permit. And then finally (and reluctantly) she stamped me in the way I had asked from the beginning. What an interesting experience 😂. Honestly tho, based on their disbelief and reluctance, I'm beginning to think that my case officer at opec has lied to me about insisting that to be a teacher for a language school, I have to be on a type b.

im aware of this, and have always insisted on a Type O in the past for this very reason. but this time it seems it was definitely the OPEC officer's stubborn insistence and general incompetence is to blame this time. Thanks anyway 🙏

I think that your employer wanted you to be on a Non-B to "have control" over you visa/extension wise :/

@Zayid ******

IF you were on a Non-O visa/extension based on marriage to a thai national OR raising thai children you could have stayed on that extension and gotten a work permit from the Ministry of Labor to legally work.

MANY employers don't want their employees on marriage/thai child extensions because if you're on a Non-B visa/extension they have control over your visa.. Quit and you lose the visa/extension where as IF you were on marriage or thai child extension and quit or lost your job you KEEP your visa/extension..

So if you were on a marriage/thai child extension that's why the officer at passport control didn't understand why you wanted to get off that extension and on to a Non B

John Stanners so incorrect!

Non O to LTR, METV to B/O/LTR, Nong OA to LTR, many times you change one active visa to anorher!

Vin Gadjo you dont change from a non o or any other visa to ltr, the other visa gets cancelled

Vin Gadjo he's not changing from one to the other though, he holds 2 active visas. He can ask to be stamped in on one but its going to be down to the immigration officer

John Stanners actually I was trying to change from one to the other, was forced to change it to type b mid way by my employer. Had a re-entry permit active even 😔. What a hassle.

yes it seems the active re-entry permit is what messed things up. Do you think I need to cancel it before trying to re-enter?

And to answer your q no I didn't print it out but showed it to him on my phone 😔. My thai wife was with me and helped to explain it even. Everything seemed so smooth but I forgot to check the actual date he wrote in, which would have given it away.
