Might try contacting the tourist police, if they have them up in Chiang Mai. They are group of volunteers that work with the regular police in a variety of ways and were really helpful when I first landed in Phuket. At that time they were given space at immigration they used to set up a counter to answer questions and even helped me fill out paper work before I presented it to the actual Thai immigration officers. This was a bit over 10 years ago and may have been unique to Phuket, (there's certainly nothing like this availible at immigration where I am living now), but Chiang Mai being a major tourist destination like Phuket is may offer something like this as a resource. They might not be physically located at immigration like they were in Phuket but may still be availble in their offices to answer questions. Maybe someone online here living up that way can advise. Very friendly folks made up mostly of expats who volunteer their time simply to be helpful, and like I said I found them to be super helpful especially in providing up to the minute advise on the many changes regularly encountered at immigration here in Thailand. I have a partner who speaks Thai now so am in good hands. She supports me whenever I get a little panicky at immigration, which can unfortunately happen to folks of my disposition from time to time. 555. "Calm down" she will say, "Thai people are good people and want to help". She's always been right about that... so far at least. 555

@Peter *******

If he's out of the country comming here may pose a problem but asking in Face Book is probably not his best alternative. Kund of depends on thevamount involved. It may be considerably less than a ticket.

@Simon ******

What is the interest rate you are seeing? Sounds pretty good.

Read a few years back that around 25 million USD was required to have a bank "care" very much about a particular account. (That's close to 800 million Thai baht). Go show them who's the boss.

Give me 10k and I'll tell you. (Spoiler alert... yes it's too much).
