I am currently on a one year extension based on marriage to a Thai and in about 3 weeks I will apply for the same extension at Chiang Mai using a 400k baht security deposit as evidence of income. May I ask, please: have the requirements for documents to submit changed over the past year? (I live about 3 hours away from the city and have no plans to visit before I apply so I cannot check at the immigration office myself and they haven't answered their phone.)
The image shows the required documents list at Chiang Mai Immigration Office from November last year.
TLDR : Answer Summary
The user is inquiring about potential changes to the document requirements for a marriage-based visa extension at the Chiang Mai Immigration Office, specifically concerning a security deposit of 400,000 baht as proof of income. They mention they are currently on a one-year extension and due to distance, cannot visit the office to verify the latest requirements. Comments from others suggest that documentation like a new Kor Ror 2 may now be required and emphasize keeping banking documents updated.
