What are the requirements for a one-year Non-O visa extension in Thailand, and can I use a different immigration office?

To get a one year extension of stay based on raising half-Thai children, you will need the following:

1. Your passport and a copy of:

- Your data ("picture") page

- Your Non-O visa

- Your entry stamp

- Your departure card

2. Your child PHYSICALLY next to you, and

- Her ID card and a copy of her ID card (OR passport, OR houseboat)

- Her housebook, and a copy of the first page

3. To meet the money requirements, which are:

- 400K THB in a Thai bank account, *NO SEASONING REQUIREMENTS) OR;

- 40K THB in income OR;

- a letter from your embassy saying you make 40K THB a month

4. Proof of custody rights (either the rose border certificate, OR a translated copy from your home country OR court documents showing parental rights)

5. The application form

6. 2x passport pictures

7. 1,900 THB for the processing fee.

Different immigration offices have different requirements, and may include:

- A copy of the TM30 filed where you live

- A hand drawn map to your house

- Witnesses or interviews with neighbors

- Rental contract (if renting property or a condo)

But the OP wants an one year extension of stay based on raising half-Thai children.
