Had been here for several years on Non Imm- O based on retirement, changed last year to based on marriage. What docs are required for my annual extension?

TLDR : Answer Summary
To renew your Non-Immigrant O visa based on marriage, you will need to submit a set of documents that typically include copies of the TM 6 form, all passport pages, two TM 7 forms with passport photos, copies of your marriage certificate, proof of income (either 40,000 THB per month or 400,000 THB in the bank for at least two months), a TM 8 form (house owner form) with ID and house book copies, six recent photos (including one of the front of your house and mailbox), and a hand-drawn map to the immigration office. Additionally, you'll need new bank letters and new pictures since this is an annual renewal.
