I just renewed my passport at the US Embassy Feb. 5..I had an appointment and on my appointment card it said passport services. I was promptly helped with no wait, the lady who helped me gave me the option of keeping my passport although it would have to be cancelled by punching 2 holes in it and they would mail me a new one that is arranged with the post office on embassy grounds or keep my passport and then mail it in prior to receiving my new passport. Process was very quick, I paid in Thai baht and now waiting for new passport
