I didn’t do the swap to the new passport until I had to do my next extension, about 4 months. SCB first, took 10 min so new bank docs had the new number. In Korat, they elected to do transfer and extension all at once, really no dramas.
My home is here is Isaan, the Embassy website had the online form which I downloaded. Passport sent to my “ home” address as Will27 stated.
You can elect to pick up the new Passport from the Embassy if you wish.
I just did it entirely online from home here. Quick visit to local photo shop for pictures then sent all online. Just make sure they don’t photoshop to enhance. Received new Passport in about 4 weeks. No need for Agent, only 1 page to fill out.
I drove on the M6 from Pak Chong to Korat 2 days ago. It finishes at the moment on the ring road around Korat. Easy to go North or East from there. Toll gates are being built now so still free, probably another 6 months or so. All 80 Km/H posted but most traffic at about 110Km/h. Sign saying only 4 wheel vehicles allowed.

If you're concerned about corruption you're in the wrong place.”
Honestly, I don’t think the issue is about corruption, it is about the legality of one’s extension if properly audited, following this corruption.
