I have a question that does not effect me but maybe a lot of others. If you have the type of visa which requires border bounce and say you still have 9 months left on that visa, (and clearly border bounce is not an option) will getting an extension based on Thai spouse void that original visa?
TLDR : Answer Summary
The original visa will not be voided by obtaining an extension of stay based on marital ties with a Thai citizen. Extensions can be sought without affecting the existing visa, and while the extension process requires the spouse's presence, it provides an additional way to extend your stay in Thailand.
