How can I efficiently obtain a retirement extension and multiple reentry permit at Nonthaburi immigration?

Third retirement extension and multiple reentry permit at Nonthaburi immigration. In and out in 75 minutes;

1. This immigration office allows you to book 45 days in advance of your stamp expiration.

2. Definitely helps booking appointment in advance and booking first appointment for 8.30. Bring a print out of the appointment booking.

3. Need 2 printouts of relevant passport pages. One for retirement extension and one for reentry permit.

4. For first time, they wanted signed photocopies of previous 12 months bank book transactions.

Very efficient and friendly immigration office 👍.
