How can I extend my Non-O visa based on marriage to a Thai citizen with upcoming travel plans?

Another thing to consider

@Ma**

would be to go to the immigration office with your thai wife, explain that you travel like you do, and SEE if they'll give you a longer "under consideration" period. I had an acquaintance who needed to go to the US during the under consideration period after he applied for the year marriage extension. He talked to the office when he applied for the extension and got a TWO month under consideration stamp, he bought a re-entry permit, left and came back just before that stamp expired.

It's worth a shot for you to ask as you're out nothing. If they can't do it you should still see if the thai consulate in Indonesia will issue a year-long, multi-entry Non-O visa. Because otherwise you're going to be buying a 90 day single entry every time you enter the country.

You do realize that as it is now you're going to go thru the same entry procedure getting back in every time (covid-insurance, negative covid test, fit to fly, COE, repatriation flight back, quarantine, etc)

What I would say IS when you do go to Indonesia (where you'll have to apply for a new Non-O visa and permission to enter just like you did already) I'd see if they will sell you a year long, multi-entry Non-O visa (some consulates WILL do it) AND that way every time you enter the country you'd get stamped in for 90 days for the whole year the visa is valid for

Sadly, you won't have enough time to apply for a yearly extension before you have to leave.

You can apply for a yearly extension at many immigration offices when you have 45 days or less left on your current entry stamp from the Non-O. (and some offices allow you to do it only when you have 30 days or less left on your current stamp)

BUT

When you do apply you will get a 30 day under consideration stamp and then you come back on that date to get the year extension inked in

Time wise it doesn't work out because you'll have to leave the country before you would have to go back on the under consideration stamp date to get the year extension..
