appointment for long-stay extension necessary for ChiangMai Immigration?

[Presnock]

I have read via this forum that some people do an appointment while others say it is not necessary.  I did my last two extensions, going to my bank first for copies of bank letters (I do 3 - sole ownership of acct, 12 monthly deposits, and the bank's credit advisory (of my deposits 12), updating my bank account book, plus all pages from my bank account book; then off to immigration getting there around 10 AM and those

past 2 years I was in the bank less than 40 minutes and didn't have an appointment.  I notice on the CM Immigration page, an appointment calendar which seems to have originated in January.  I am wondering if it is necessary for me to get an appointment or just show up at

immigration.   Has anyone not having an appointment had any problems getting service lately?  Appreciate any response.
