Can I renew my US passport by mail while I'm outside the country?
No, you cannot renew your US passport by mail from outside the USA (except in Canada.) You must do it at the nearest US embassy or consulate. From US State Department website: If you live in Canada, you may be eligible to renew your passport by mail and avoid a trip to a U.S. embassy or consulate. If you live in any other country, you must renew your passport at a U.S. embassy or consulate. Renewing US passport by mail Applying outside of USA
