When should I apply for an extension of my Non-O visa in Thailand and what documents are required?

Dec 16, 2025

a day ago

Hi, I'm on my 90-day Non-O visa, the 800k THB deposit should come in before or around Dec. 18, an exact month after my entry.  I plan to extend my stay to a year.  Many thanks to great advices from this group.  My questions are :

1)  when should I apply for an extension to a year ? 

2)  if I wait for my deposit to reach 2 full months and then apply, will I have enough window between 2-month deposit  vs.  90-day stay ?

( I really don't want to leave the country and then re-apply for 90-day Non O )

3)  are health insurance、criminal record from one's country required for the extension.

4)  my Thai bank did not ask for address certificate and I successfully opened an account.  Would I still need to apply for address certificate for any purpose ??

K-Bank at EmQuartier shopping mall did an excellent job, no address certificate needed、no hassles、very helpful staff and open on weekends.  I strongly recommend this branch !  💪💪

Million thanks !  🙏🙏

TLDR : Answer Summary

The poster is seeking guidance on extending their 90-day Non-O visa in Thailand, specifically about the timing for applying for a one-year extension, the necessary bank deposit duration, and required documents like health insurance and address certificates. Comments provide clarity on needing the deposit to be in the bank for at least 60 days before applying, reaffirming that health insurance and a police record are not required for Non-O, and suggest checking with immigration for necessary documentation.

I believe the rules are you have to have the 800,00 in the bank for 60 days before you apply for the extension, you also need to have at least 2 weeks left on your original 90 day visa before it expires? You might have to leave, ask your immigration office

No health insurance or police checks required for a 90 day Non O visa only required for a non OA

With these many questions I'd certainly enlist the services of a Visa agent. I have one that I use for anything immigration related. Ensures no time wasted and stress-free.

The money has to season for a full 2 months date to date. On that day you can go to immigration and apply for your one year extension. What date is your current permission to stay stamp? No health insurance or background check requirement, insurance is always a good idea though. You need to make sure that the TM30 has been filed by your landlord, check with your local immigration office to see if they want to see your lease when getting the extension. You'll need the residence certificate from immigration if you want to buy or sell a motorcycle or get a Thai driver's license etc, they're good for 30 days.

Currently I cannot with the 90-day Non-O.

it's good for the duration of your current stamp so that's why you wait until you get the full extension before you buy it.

hope for the best, you have 2 days. I may be wrong but, if for instance the money is a day late you might be able to pay the overstay fine and complete the extension.

Immigration should have a checklist for you. If you have any questions about the checklist, I would ask them.

Money needs to be in a Thai bank account for 60 days before you get extension. You are cutting it close, if not too late. Get a list of what you need from the imagration office.

it's not 60 days, it's two calendar months

Regarding when to apply.... You apply after the 800k has been seasoned for two months.

For you that means almost expiry of your 90 day entry stamp.

Why did it take a month to open bank account and transfer the 800k
