How can I extend my Non O visa based on marriage in Thailand?

Good morning, I also need to apply for the extension of my one year visa based on marriage. I stay in Phu Kradueng that is in Loei Province but I'm near to Khoen Kaen than Chiang Khan were the Loei immigration office is located. I must apply in Chiang Khan (were I got my marriage visa before) or I can go to Khoen Kaen?

, you go to Chaengwattana Section L to get any extension on a Non-O based on marriage. You can either apply for a 60 day visit thai family extension (which you can get once per entry), or you apply for a year extension OR at this time you could get a 60 day covid extension.

To get a one year extension of stay based on marriage to a female Thai national, 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 wife PHYSICALLY next to you, and

- Her ID card and a copy of her ID card

- Her housebook, and a copy of the first page

3. To meet the money requirements, which are:

- 400K THB in a Thai bank account, seasoned for 2 months OR;

- 40K THB in income OR;

- a letter from your embassy saying you make 40K THB a month (if you're from a country that allows the letter, you can not show income. Not all embassies offer this letter)

4. Marriage certificate (either the rose border certificate, OR a translated copy from your home country)

5. The application form

6. 2x passport pictures

7. 1,900 THB for the processing fee.

Different immigration offices have different requirements, and this may include:

- A copy of the TM30 filed where you live

- A hand drawn map to your house

- Pictures of you and your wife in various locations in the house (front of the house/ condo, in all rooms, etc)

- Witnesses or interviews with neighbors

- Rental contract (if renting property or a condo)

What immigration office are you using?
