Will leaving Thailand with a pending visa application affect my status?

What about the (potential) home visit?

I was told by CW that they might come for home visit, and phitsanulok immigration that there would be 3 home visits. I understood they don't make an appointment, just phone 2 hours or less before arriving, and if you are not home for their visit they just cancel the application.

Hence, I understood during the under consideration period you can't even travel to a different province without risking missing the home visit.

Note: I did apply for the one year extension based on marriage to Thai wife at CW in December 2024, and we did not have any officer visit before going back for stamping at the end of the under consideration period.

This is how it works,

IF you have applied for an extension, received an under consideration stamp but need to leave the country, you would have to buy a re-entry permit (which is ONLY valid for that under consideration stamp)

AND

it goes without saying but I'll say it anyway 😮 you have to be back IN thailand by the date that stamp runs out or you lose the application for extension and start all over from zero again.

Plan your trip for the time after your extention is stamped in

If your stamp is still valid I believe you can with a re entry as long as your back in time

I have departed Thailand with an Under Consideration stamp for a Thai Wife visa extension (and re-entry permit) and then returned to go to immigration on the required date ... no problem.

You say visa application. Do you mean NON O visa, or extension of stay? Marriage or retirement, and which office? You can leave during both, with a re-entey permit, but you will have to be very up front with immigration. If it is a marriage visa or extension, some offices want to visit your home. Return to the office on the review date and you will be fine.

You need to attend Immigration on the date indicated on the under consideration stamp or your visa/extention of stay will be denyied.

I think you can get a re entry permit to your under consideration date, only one way to know for sure, go immigration and ask for a re entry permit

IF you have an Under Consideration stamp in your passport...you are required to report to the Thai Immigration office on the date shown on the stamp in your passport.

Failure to do that means your application for the extension will be DENIED.

It's wise to stay in Thailand uh until you have the extension you applied for is approved and stamp in your passport.

You will have to start all over with applying for a Thai Visa.
