However, you can create compound nouns with "passport" to describe specific types or aspects of passports:
* Passport control: The area where passports are checked.
* Passport holder: A case or wallet designed to hold a passport.
* Passport application: The form used to apply for a passport.
* Passport photo: A photograph required for passport applications.
If you can tell me what you're trying to describe, I might be able to give you a more specific compound noun suggestion.
