How long does it take to get a decision on a Non-Immigrant O visa extension application in Thailand?

@Jon ****************

, you can get a multiple reentry permit on the same day, costing bt3800, or, what I would suggest is getting a single reentry permit at bt1000, and if, because of all the quarantine expense and hassle, you don't return more than three times during the year, you would be wasting money. If the covid-19 situation changes you can always get a multi-reentry permit later. Just so you have at least a single re-entry permit when you leave, you won't loose your extension, then decide later if you will actually need one because of this virus. But either way, you can get it on the same day, and it is recommended.

@Daniel ******

the exact date.
