As I read today's post on the new, online 90 day reporting system, a little tingle in my brain went "90 day?"  Whoops, quick PP check revealed due Nov. 30...duh.  Realized too late to get done today but I have a few questions.

 

-Is 90 currently at MTT or CW?  I did my last 2 in Jomtien but am back in Bangkok now.

 

-Are they still having Saturday hours or did that end?

 

-Is Monday, Dec. 6 a holiday? Immigration closed?

 

-If closed and I go Tuesday, Dec 7, and my due date was Nov 30, are they likely to give a day of grace for the holiday closing or will I be overdue.

 

-What is the overdue fine for 1 or possibly 2 days.

Mueang Thong Thani.

In person can report 7days post due date.

BTW the fine is (can be 2000 baht)

Edit: notice that your "back in Bangkok" you will need to file change of address TM30.

The are not open on Saturdays now.

They are closed on monday the 6th. 

Every day counts including holidays and weekends.
