It takes around 8 weeks to renew your passport through mail. Expedited passport renewals by mail will cost an additional $60 in government fees, and takes 2-3 weeks for processing.

You will need your current passport, fill the DS-82 form online, a passport photo, photocopy of driver's license, flight itinerary, proof of name change, and you will have to pay the renewal fees.

If you are in a rush and need to renew your passport immediately, you can visit a US passport agency that is located in the major US cities, and it will be renewed on-site.
