What should I do if I lose my passport while in Thailand and need to update my visa?

in january, i was on my way back to work and had to spend the night in bangkok, I had my passport in the same pocket as my cell phone, needless to say i lost my passport. went to police to do a report, also was very lucky to get an appointment at the consulate the next day.... while applying for my new passport I was given a letter stating the details of replaced passport, and was told I need this when I apply to get visa stamps in my new passport...

I had to leave thailand as soon as I recieved new passport and didnt have to time to go through the process of updating my docs.. So when I get to where I work, of coarse my docs need to get updated and immigration wanted the letter from the consulate, with the impression I would get it back... Now they refuse to return it, which is causing some huge grief. Ive finally had my passport returned, but not the letter.

Im now trying to get a new letter from consulate, but havent gotten very far, hopefully they will issue another one, but Im not counting on it.. I'm hoping Thai immigration will accept a copy of the letter when applying for new stamps....

never loose your passport, its a horrible situation to be in, im still months away from clearing most things up... but the clincher is the Retirement visa stamp..
