My retirement visa is due for renewal on Monday 13 Jan 2025 in Chiang Mai. I was planning to fly out of Thailand for 4-8 weeks on 9th or 10th. Can I apply for my extension early or do I have to be physically in Thailand on 13th?

Thanks in advance for advice

Im currently in CM on a STV, due for the final visa extension next month. Its my understanding this is single entry, is there any way around this as I'd like to go away for 1 week without losing the remaining 3 month extension? Thanks.

Follow up question.. Here on an extension of an OA visa. I want to travel. Did not a file on reentry form.

Is their a multiple reentry available or do I need to purchase a separate reentry every time I leave. And does there have to be an exact reentry date. Say I want to travel for a wile in a different country but I don’t know when I will return.
