@Wayne *******
Why do you post such a nonsense?
*** a 90-days single entry Non-O Visa has a visa validity of three months from the date of issue
*** if you enter 4 weeks after the visa got issue, you will get stamped in for a 90-days stay permit
*** the visa itself becomes INVALID for further use upon entering Thailand
The visa is a single entry type, which means you can only use it for ONE entry. Which further means that is becomes invalid after you have already entered Thailand ONCE.
*** you are now inside Thailand on a 90 days stay permit, and the visaclass you used when you entered, is marked in the upper right corner of the entry stamp.
The VISA itself is expired, invalid, used, void . . whatever you may call it. The visa has been used, boom, over and out
*** this means that you stay permit is linked to the Non-O Retirement Visa. However you are inside Thailand on a stay permit, not “on a visa”.
*** The visa cannot get “extended”, this is technically not possible. The only thing that gets “extended” on Immigration is the STAY PERMIT
*** this means you are able to apply for the “Extension of the Stay Permit Based on Retirement” up from 30 days before the 90 days stay permit expires
*** Check the “extension” stamp. WHERE on this stamp can you see anything mentioned that says “visa”? You won’t find it, because this stamp is a stay permit and not a “retirement visa”
