It might be able to apply for a Non-O dependent to a Thai Child with the right income and age if you are living together. Just your name being on birth certificate might not be enough. You may have to have parental rights to the child.

The age rule is a father/mother has to be 50 yo or over as a dependent.

Go to the local immigration office to get the detailed requirements.

In Bangkok, the 90-day reporting counters are at the Chaengwattana office (not at the IT Square Laksi Plaza office) counter A for walk-ins, and Counter B for those who have online bookings. (Except for people who are under BOI or on Non-LA)

Someone might be confused as Chaengwattana Government Complex is also in Lak Si district (means "Lak Si" words in its address).

, Taipei moved to eVisa system from this 1 January 2025. They don't accept walk-in/in person application any more. They state processing time is up to 15 days now.

Parents are not eligible for DTV dependent. Only a spouse and children under 20 years old can apply for it.

Especially in Bangkok, you have to go to the Chaengwattana office for a yearly extension after the under-consideration period on the exact day they directed.

you better talk with your employer in advance as well. You will need some company-related documents including those they get or get certified from government agencies when you use monthly income from legally working in Thailand, not only your own personal tax document and contract. If they don't agree to provide them, you cannot use monthly income in Thailand as your financial proof. Get the latest requirements about this point from your local immigration office before you talk with your employer.

@Christopher ******

, If you use the 100% banked money method to meet the requirements, you need a transaction record for two date-to-date months as of the application date. Otherwise, means if you are using the monthly transfer method (if your office approved your case), you need the record for 12 months.

, only the officer at passport control who will handle your entry can answer to your question correctly.

Thank you for the report. It has been just more than a half year since "90-day reports in person after travelling out of Thailand" was introduced. And seems a bit immigration office-specific.

If your bank passbook has every single transaction record separately, no "sum up" deposit or withdrawal record, a copy of your passbook (updated on the day of application) with meeting minimum balance for each month along with a bank letter would be sufficient.

You have to provide two months' transactions as of the application date if you use all banked money methods. Otherwise, you will need 12 months of transaction records.
