30 day extension - Samui Immigration -

Could someone remind me of the documents I need to complete my 30 day extension in Samui? On a tourist visa.

Thank you!!

Recently moved to Hua Hin from Lampang, and had some conflicting info on what was required for extension of Non O (retirement) by the HH Imm. Office. Got it done the other day, and the following was what I submitted and accepted. TM7 with photo, copy of passport front page, copy of old visa, copy of TM6, map to residence, copy of House Card of house owner, copy of ID card of house owner, 3 month bank statement, bank letter dated same day, updated bank book. (All for the 800,000 deposit requirement). Got an online queue appointment prior to the day. There is an online queue desk at the office. I was served immediately and on time. 20 minutes later, left with new stamp for another year.

Hello, what are the documents required this month for the 60 day extension with the Samui Immigration? I've called their number, but the message is in Thai and there's no redirect to customer support.

What documents do you need for 30 day tourist visa extension and is there only one immigration office in Bangkok that you can go to to extend?
