Can i mail a diplomatic passport for personal passport application

I think there may be some confusion here!

A diplomatic passport is a special type of passport issued to government officials, diplomats, and other individuals who need to travel abroad for official business. It's not a type of passport that can be used for personal travel or applications.

If you're looking to apply for a passport for personal travel, you'll need to use a standard passport book or passport card. These types of passports are issued to U.S. citizens for the purpose of international travel and are not related to diplomatic or official business.

To apply for a standard passport book or passport card, you'll need to submit an application, supporting documents, and a fee to the U.S. Department of State. You can find more information on the application process and required documents on the U.S. Department of State's website.

It's important to note that diplomatic passports are not available for personal use and are only issued to individuals who have been authorized to hold one by the U.S. government. If you're unsure about which type of passport you need or have questions about the application process, I recommend contacting the U.S. Department of State or a passport acceptance facility for guidance.
