No idea about DC embassay, but Nepali Embassay in PRC, Beijing deserve praise for their dutifulness. I don't know about any other's experiences but mine was a fine one. Documents sent on mail (as instructed by an official, who was very helpful), including the fee of pasport renewal, documents arive safe and sound within a week. Nice work, appreciate their duty execution, hope and belief they will keep up with the nice work, and others, elsewhere will learn and change for good.
