I'm not sure I'm following you, as I believe we are on the right track. My understanding is that the Visa and permission to stay are two separate entities and that the dates do not need to correspond to each other. For example, if my visa was issued on January 1, 2024 and expired at the end of December 2024, I could technically enter Thailand anytime during that 12-month period. If I arrive in Thailand in late December, just a couple of days before the visa expires, I could still potentially be stamped in for 12 months. If I leave the country after the visa expires, it then becomes null and void, and if I want to re-enter Thailand, I would need either a new visa or enter using the visa-exempt program. In my partner's case, she wants to apply for a DTV, but can't do so on her upcoming trip home as her OA Visa will still be valid, thus making her ineligible to apply for another visa. Since it looks like we can't cancel her visa, she will travel to her home country in May and return in June on her existing OA visa/stamp, which both expire in August. While she's away, she will purchase another 12 months of Thai insurance so that when she returns in June, she can hopefully receive another 12 months' permission to stay. Technically, she only needs a few months as she will be leaving Thailand again in December. When she leaves in December, she will no longer have a valid visa, so she can then apply for a DTV in her home country. That's our understanding, so if we are wrong, please help us to understand why. Thanks.
