我现在人在中国，签证有效期快到了，能把我的美国护照交给朋友帮我带回美国，到你们的签证办公室重新申请新的签证吗？
I am now in China, and the validity period of my visa is coming soon. Can you give my American passport to a friend to help me bring it back to the United States and go to your visa office to re-apply for a new visa?
No.
You must leave the country before the validity of the visa and then re-submit your visa application or apply to the local public security agency for an extension.
