ORIGINAL POSTERHi, 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 user seeks advice on extending their 90-day Non-O visa to a year, questioning when to apply for the extension, the timing of their bank deposit, and requirements such as health insurance and address certificates. Community responses indicate that the deposit must be in the account for 60 days before applying for an extension, ideally just before the 90-day visa expires. Health insurance and criminal records are not required for the Non-O visa extension.

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

you can apply for an extension right up until the very last day of your current stampJeff *************

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.

With the one year extension, will I be able to freely leave and enter Thailand ?? 🤔😲Currently I cannot with the 90-day Non-O.

you will buy a reentry permit once your extension is inked in. 1000 baht single 3800 baht multipleYaoyu ***********

Thank you again ! 🙏🏻 Is 3,800 THB is good for a year !? 🤔Wannikea *********
@Yaoyu **********
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.Reply to

Thank you ! 🙏🏻 I entered on nov. 19th, wired money yesterday, and the stamp will expire on feb. 18th. 🥹Wannikea *********
@Yaoyu **********
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. @Tod ********
can you comment on this?Reply to

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.

@James *********
it's not 60 days, it's two calendar monthsReply to

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

Can you confirm which extension your applying for ? A Non O or Non OA? The OA need the insurance and police certificate. The Non O does not.
