90 day Notification
This post is just for information:
I tried to do my 90 day notification online twice, TM 47 notification of 90 days overstay, but got rejected because I was supposed to go there the first time in person Immigration division 1 @ chaeng Watthana. I took bts, transfer wat pra si matthat to pink line platform 2 towards civic center off at government complex.
**make an appointment in advance (3 weeks)
Because I had to wait over three hours without an appointment.
The process took only about two minutes and they issued a receipt (see pic). Just be careful to do it in time because you could get a fine of 2 to 5000 baht.
I really hope it works next time online so I don’t have to come back just for this.
It would be much much nicer if you didn’t have to go in person the first time but if you do, please make an appointment three weeks in advance because sometimes the appointments aren’t available & you could be there for three hours or more. Also, there aren’t enough seats & bring your own pen because they won’t let you borrow a pen to write the form. I have a Thai marriage visa and still have to do this.
