What are the repercussions of being one day late filing for NonOA extension at Chiang MaI. Bank one year statement may not arrive in time from Bangkok Bank.

I’m coming up to a year in country on my PE (elite) visa. I have contacted customer services asking what I need to get an extension, and customer services sent me the following list:

2 Inches X 2 Photos

Departure Card (TM.6)

Elite Membership Card

TM 7 form for stay extension, STM2 and acknowledgement of overstay penalty

The receipt of TM 30 (Notification of address)

Service Fee 1,900 baht paying to the immigration officer.

Passport with valid Elite visa

My question is, does the above cover it all, and is there anything else I should be aware? no requirement to get some paperwork/stamp from MTT before I head to cheangwattana, for example

Which section do I need to queue at?

I just want to avoid the need for multiple trips to cheangwattana if possible.

TIA
