I've been told that it you are over 50, you can put 800,000 baht in a Thai bank or show 65,000 baht/month income to get a one year, renewable visa.

No, your absolutely correct. My main point was, you may get away with it, but why chance it if you don't need to.

Somewhat unrelated, I took a trip to Honduras several years ago with only 2 months on my passport and immigration in the US said they would let me go, but don't be surprised if they don't permit you into the Country. Honduras immigration didn't give it a second look. I guess your friend would be taking his chances. I think the biggest hurdle would be getting past the departing flight immigration, as long as the passport had sufficient time before the returning flight, you would probably be ok in the host country.

If it was me and I had time, I would opt for a new passport. Why take the chance if you don't need to?

Thanks Tod

Yeah, maybe I'll just plan on a 6 or 9 month visit, before making any permanent decision.

I was told you had to show 800,000 and renew every year, but the 800,000 needs to be in the bank 3 months before renewal. The visa process is confusing there.

10 million? I thought it was 800,000 baht for the year?

Yes, but those funds are still yours when you leave.

Discussed that before. A bit pricey for me.

I guess if you put the required money in a Thai bank, it wouldn't be too bad from what I understand.
