Is there a minimum passport validity requirement when applying for a non-O marriage visa extension in Thailand?

When applying for a one-year extension of a NON-O (marriage) visa in Thailand, immigration requires that your passport must not expire before the end of the extension period. If your passport is due to expire in less than a year from the date of application, your extension will only be granted until your passport's expiration date. Additionally, while many countries recommend having at least six months of validity on a passport for international travel, if you are staying in Thailand, this may not be an immediate concern. It's important to note that if your extension is tied to an expiration date, this will affect future visa applications when you renew your passport.
