2026 Guide: Thai Marriage Visa Extension (Non-O)
I successfully received my marriage-based visa extension today! However, my first attempt earlier this month was rejected because I was missing a specific document: a Police Clearance Certificate. To save everyone else from wasting a trip to Chaeng Watthana, I’m sharing the exact requirements and the lesson I learned the hard way. If your nationality requires a police report, please note that you need to start the process at least 45 days in advance.
