I come from Neijiang, Sichuan. Can I get a passport in Chengdu, Sichuan?

It doesn't seem to work. I have to go back to the issuing authority. That's what I used to do.

You can go back to Neijiang to do it. When you come out, ask your friend to take it for you and send it to you.

It usually takes a month to get it.

When you go to do it, you should bring your household registration book and ID card, which seems to be around 200 yuan.
