, You definitely want to ask them, bringing your travel information.

Jomtien has a 30-day application window in advance. If I remember correctly, Jomtien can give you extra days in the application window in case you show proof that you will not be in Thailand the whole of the standard 30-day application period. It could be up to 40 days in advance or so.

Usually, a set of one-year transaction history AND a copy of your passbook updated on the day of your application works.

Check with your local immigration office.

To do this, submit a 1-year transaction to your bank, AND update your passbook immediately to avoid a lump sum log after your transaction.

Then, update your passbook on the day of your application to the immigration office.

You might need to deposit/ withdraw a small amount of money to record a clear log on your passbook.

You have to talk with your employer about the procedures/documents to apply for your baby's visa, especially if you are going to do it inside Thailand.

There are companies that don't (or cannot) support employees or family members if they are overstaying or illegally staying in Thailand for their own reasons.

Better be careful to think no problem for children to be overstaying, especially if the main applicant is a Non-B holder.

Technically, yes, it's within 72 hours before arrival, but the system is open for 4 days including "today" as a window for TDAC submission. (day counts at 0:00/ midnight ICT).

Check and try

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.

, 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.
