What documents are required for a second two-month extension of a visa in Thailand?

To apply for a second two-month visa extension in Thailand, you will generally need the same documentation as for your first extension. This includes a copy of your passport's data page, a copy of your last entry stamp, the TM6 form, a filled-out TM7 form, a filled-out STM2 form, the 'Unable to travel due to Covid' form, proof of TM30 registration, a passport photo, and a fee of 1,900 baht. It's also noted that if you are stamped in until a certain date, you may need to leave the country unless an extension is granted.
