How many days of extension can you get on a family visa in Thailand?

you can enter on a 90-days Non-Imm-O Family visa, get stamped a 90-days stay permit, and on Immigration can get a 60-days extension based on "family visit" for 1900 Baht. Nobody is forcing you to extend your 90-days stay permit into the 1-year Extension of Stay Permit. However before the 90 plus 60 days = 150 days stay permit expires, you need to exit Thailand. You can't get another 60-days "family visit" extension any more - the limit is ONE per entry

For the family VISA, which means a 90 days Non O based on marriage or having a Thai child, you may apply for the regular one year extension of stay OR a 60 days family EXTENSION visiting thai family.

If you’re on a 60 days tourist visa or 60 days visa exemption and also are married to a Thai or having a thai child, you can also apply for a 60 days family EXTENSION visiting Thai family.

ok if your on the 90-day Visa based on family you may be granted a 12-month extension of stay. Your extension of stay will start after your visa expires
