Hello Rob,
Thank you very much for your response, and apologies for not replying earlier.
My employment has already been terminated, but my employer is holding off on canceling my WP for about another week. They've also mentioned that they could delay canceling the visa extension for about another month, though I’m not entirely clear on how that process works.
Based on the preliminary information I received from the immigration office, the Non-O based on retirement does seem like a much easier option. To apply for the one based on marriage, I would need, among other things, a marriage certificate (translated and legalized), which is quite a lengthy process (we married in Europe).
For this reason, I’m leaning towards applying for the retirement-based Non-O. My question is: if I switch to a Non-O based on retirement and later receive a job offer, would it be possible to then switch to a Non-O based on marriage to be eligible to work? Or would I need to apply for a completely new visa?
Regarding Thai Social Security, that's a good point. My company has been paying it, and I’m planning to continue. I visited the SSO, and they told me I have until the end of the year to make the payments. I’ve also started gathering the necessary documents to apply for the yellow book, which includes a birth certificate (quite a hassle to get).
Thank you again for your help!
