If you go through passport control at immigration at the arrival airport, you need to have a proper visa and a TDAC submission.

There is a check box to indicate whether you just transferred on the second page of the TDAC web system.

@Karl *******

, don't you have a 1-year stamp until july 8, 2025, after using a 60-day family visit extension last year?

@Karl *******

, when did you apply exactly for a new 90 days Non-O visa, then when and how many time of following 1-year extensions?

Basically, yes, you are expected to submit the first 90-day report after arriving in person at the local immigration office. In many cases, those "first reports after entering" online submissions are rejected, but it seems some offices accept online submissions. There is no harm in trying online first within the reporting window, which is between 15 days and 7 days before the due date. If rejected, you can visit the local office to submit in person within 7 days after the due date.

@Karl *******

, If you have already used a 60-day family visit extension with the current series of visa and extensions, you cannot apply for it again. 60-day family visit extension is a one-time deal per visa.

@Karl *******

, you need "proof of being inside Laos" to complete the application. Usually, it's an entry stamp to Laos.

No, unfortunately, Savannakhet or any other place no longer accepts in-person applications. All Thai embassies and consulates are now on the eVisa system. You go to one of the neighbouring countries, apply for a visa on the eVisa website using an entry stamp for that country, wait for your visa to be issued, then return to Thailand.

It's working fine.

Make sure you are accessing the correct site.

@Ron *****

, no application is required to get the second year directly from Non-OA visa. It’s just another entry stamp.

Didn't you use e-gate (automatic gate) when you left Thailand last time? It just shows that you don't have a departure stamp since you went through the stampless e-Gate for the latest departure, still, your arrival and departure history are correct and legal.
