When can I apply for a 1-year extension on my Non-O visa based on marriage in Thailand?

Sorry to butt in on your post.

Samut Prakan one of the strictest offices. (Almost pedantic one could say).

Dot your i’s and cross your t’s.

Forewarned is forearmed.

Just trying to help.

You need to check with your local immigration office. Most offices let you apply for a 1-year extension based on marriage when you have 30 days or less remaining with your entry stamp on Non-O marriage. Some offices such as Bangkok, Chiang Mai, Phuket, and a few others accept your application for an extension when your stamp has less than 45 days.

Go to your local office in advance to get their latest requirements for a 1-year extension based on marriage to a Thai. Each office has its own list, including seasoning of funds.
