Hello folks ... I received my annual Non-Immigrant visa extension at the Chiang Mai Immigration Office this week based on having a Thai wife. We submitted the application ourselves. I use the 40,000thb per month financial option. I am sharing a list of the documents submitted with my application in hopes of it helping someone else ... every applicant's list may vary depending on the current requirements, location, and IO processing your application ... (Note: Last year we had to include my wife's first name change and both of our divorce decrees from previous marriage ... the IO pulled them from the package this year ...)
