I agree, as long as I get a permission to stay stamp good until I get my extension stamp then there is no stress at all in my mind concerning a petty 30 day wait. IO is 40 minutes away even out here in the sticks along the Mekong. We go into the Provence capital once or twice a month anyway.
Like you said, everything I need is scanned into the laptop with my own scan printer. I print one selectively collated. Again full collated. Two stacks, one with a sticky note stating Originals. The IO stamps every page with a signatures stamp. Then goes through page by page pointing where each signs.
My life here is not so so complicated that I have to worry about silly little things like waiting 30 days or even 90 day reporting.
I am very glad that we don't have to fly and stay in Bangkok anymore. It's well worth doing all of the minor bank stuff to avoid what's really otherwise a stressful hassle. I hated living/working in NYC and Atlanta so Bangkok definitely has nothing I want.
The bank takes the 100฿ bank fee out of my account for the two letters and they do a final bank book counter update that shows the transaction.That's all IO is looking for. No deposit is needed. I plan my annual bank statement to receive the day before my chosen application date so I can print a copy. But I have been getting it early and we just go the next day. The kr2 is already been picked up, scanned, and print one. Insert in stacks
Maybe other people's lifestyle is more complicated but I came to Thailand to retire and live a worry free life in my wife's Mekong village. It didn't take me long to quit stressing out about Immigration. Although I have enough monthly income for a retirement extension, we choose marriage. That pleases my wife for many reasons. It is like a status symbol to some of her friends and family.
The only downside to marriage extensions is that the passport pages do get used up quicker but getting another passport is just a postal EMS mail out, thankfully. My flying anywhere else days are over so only IO extension stamps in my next passports.
