This is for a first annual retirement extension based on 800K in the bank.
Made online bookings for today 1:00PM for extension, 2:40PM for re-entry.
Took an early bus, concerned about traffic thru Lat Phrao, planned to get the bank statement and copies done before lunch. Bus #150 from Bangkapi Mall area dropped off at the entrance of the immigration soi at 9:45. Arrived at Bangkok Bank downstairs at 10:00, only one number ahead of me. Got bankbook updated with balance forward (no deposit needed) and guarantee letter, done by 10:15. Made copies and then went directly to the L1 counter at 10:30.
Told the nice lady I had a booking, she checked my name on the list. Yes, I'm early, but no waiting. Take a seat at #25 to go over documents - TM-30 was requested, printed screenshot from sec 38 app was accepted - then to see the immigration official, again no waiting. . Fifteen minutes to sign and stamp papers, then wait five minutes for name to be called. Visa extension complete at 11:10. Back downstairs for copies.
Back upstairs, go directly to the C2 counter at 11:20. Told the nice lady I had a booking, she checked my name on the list. Yes, I'm early, but no waiting. Take a seat, sign some forms, take a photo, go sit outside. Re-entry complete at 11:30.
Total time on site: 90 minutes.
