A passport and a travel visa are both international travel documents, but they serve different purposes. A passport proves your identity and citizenship, while a visa gives you permission to enter a foreign country for a specific reason and length of stay.
What Is a Passport?
A passport is an official government-issued travel document from your home country. U.S. citizens receive passports through the U.S. Department of State. Your passport is primarily used to:
- Prove your identity and citizenship
- Travel internationally
- Re-enter the United States
- Verify your identity abroad
There are two main types of U.S. passports:
- Passport book — valid for international air, land, and sea travel
- Passport card — limited to land and sea travel to Canada, Mexico, Bermuda, and parts of the Caribbean
What Is a Travel Visa?
A travel visa is permission granted by a foreign government allowing you to enter their country for a specific purpose. The visa is usually stamped or attached inside your passport.
Countries may issue visas for:
- Tourism
- Business
- Study abroad
- Temporary work
- Immigration
- Transit travel
Some countries require visas before travel, while others allow visa-free entry or visas on arrival depending on your citizenship.

What About ESTA or eTA?
Travel authorizations like ESTA (United States) or eTA (Canada) are not visas. They are electronic pre-screening systems required for travelers from visa-waiver countries.
How a Passport and Visa Work Together
A visa is normally placed inside your passport. Without a valid passport, you generally cannot apply for a visa.
Your passport may also need:
- Blank visa pages
- Minimum validity (often six months)
- Good physical condition
Some countries require one or two blank visa pages before entry.
