Non O - 1 year extension of stay based on retirement - Chiang Mai immigration requirements please

[MikaQ5]

Went through the process at CM last week , in and out in under 3 hours ( without any appointment)

I wasn’t asked to change documents that i produced ( which included 4 items from my bank )

A bank statement ( in my case only 6 months given as this was my first extension ,and the account was only open 9 months total ) 

A bank letter confirming my account balance over 800k 

A photo copy of an updated bank pass book (with that dates activity )

The original bank pass book 

 

And as I has suspected no need for any agent to be involved 

 

thanks to all who  replied
