Will Hua Hin Immigration Grant My O-A Visa Extension Until May 2021 If My Insurance Is Not Valid for a Year?

Hi Nigel I work for Pacific Cross Health Insurance and from experience the Immigration will grant you the visa up to your expiry date of the Health Insurance but I'd double check with your local Immigration office

If the policy doesn't last a year, the rule that governs O-A yearly extensions says the extension will be granted only up to the expiration date of the policy :( So it's no problem getting the extension, you just aren't gonna get the year.

SOME immigration offices want the policy in effect on the date you apply and have it run thru the year you're extension will be valid for

ALSO

you can apply for a yearly extension up to a month early in Hua Hin, I wouldn't burn down all the time until it's due because if you're missing a document etc you run on overstay if you can't pull it off in time,

There is no down side to applying early because they add the year to your current stamps expiration date

Coordinate your policy with your insurance company. They will adjust your policy to sync with your O-A extension.

Good luck.
