What documents do I need for my first 90-day report based on a marriage visa in Thailand?

When attending your first 90-day report based on a marriage visa at the Korat immigration office, the primary requirement is your passport. Some users have mentioned that while they had copies of various forms (like TM47 and TM6) and their entry stamp ready, these were not required. Typically, the process involves simply presenting your passport and filling out a basic information form. Personal experiences indicate that the process can be quick and straightforward, often taking just a couple of minutes.
