Many US citizens want to venture into a larger world than the states, and the opportunity to travel easily and passport-free is an attractive alternative. Although US citizens generally require a passport for international travel, several exceptions allow them to explore various destinations without one. These exceptions include US territories like Puerto Rico, the US Virgin Islands, the Northern Mariana Islands, American Samoa, and Guam. Additionally, US citizens can visit Canada and Alaska without a passport, provided they meet specific documentation requirements. Traveling directly to these destinations via air, however, may necessitate a valid passport. Before planning any trip, it is essential to review the latest travel regulations and requirements set by the respective destination’s authorities with your travel advisor.
Puerto Rico:
As an unincorporated US territory in the Caribbean, Puerto Rico is a popular destination for US citizens. Since it is part of the United States, no passport is required for US citizens to travel to Puerto Rico. Traveling to Puerto Rico by air or sea from the US mainland is a domestic journey. Puerto Rico is a beautiful island with urban and rural areas. The countryside has lush green hills, mountains, and many popular beaches. The island is blessed with year-round sunshine, providing the perfect setting for outdoor activities, such as hiking, swimming, and water sports.

Canada is the only foreign country on this list where US citizens can travel without a passport.

Traveling by land or sea between the US and Canada allows for the use of an enhanced driver’s license or a trusted traveler program card, such as NEXUS.
The Nexus Card is a trusted traveler program card that expedites processing for pre-approved, low-risk travelers entering the United States or Canada. It is jointly administered by the US Customs and Border Protection (CBP) and the Canada Border Services Agency (CBSA). The Nexus Card is available to citizens or permanent residents of the United States or Canada who meet the eligibility criteria and pass a thorough background check.
