International Travel

What You Should Know

In most cases, international travel requires more preparation and planning than travel within the United States. A passport and sometimes a visa is required, information related to health and safety are a must, travel logistics can be complex, and protection of Princeton technology is a concern. 

Travel Logistics

If you travel internationally please apply for a Princeton Travel and Expense Card.

Plan to book travel through Carlson Wagonlit Travel if your itinerary is multi-destination or complex, or through Concur if it is a round trip. Booking by one of these ways ensures you can be best supported by the University during your trip.


To travel internationally, you need a valid passport. It is good practice to ensure your passport is valid six months beyond your return date. Certain countries also require an entry visa. Check Visa Central for information about these requirements. An overview of Visa Central can be found here.

International SOS

International SOS provides emergency and support services for Princeton’s international travelers. Before you go, it’s a good idea to register with ISOS and to carry your card while traveling. You may print an ISOS card yourself, or pick one up at the Financial Service Center.

Regarding international health care coverage, all University members traveling internationally should be aware of the following:

  • Hospitals and physicians require payment in cash or by credit card at the time care is provided
  • University members are able to seek reimbursement from their insurance carrier when they return to the US
  • Even if University members seek reimbursement when they return, they need to pay for services out of pocket while they are abroad
  • Purchasing international health care coverage may enable the traveler to obtain medical care, at certain facilities, without large financial outlay prior to treatment.  More information can be found with our preferred insurer, HTH Worldwide

U.S. State Department International Travel Information

Before planning your travel, review information for country-specific alerts and warnings posted by U.S. State Department. You also may wish to enroll in the State Department’s STEP program.

Note: The Smart Traveler Enrollment Program (STEP) is a free service provided by the U.S. Government to U.S. citizens/nationals who are traveling to, or living in, a foreign country. STEP allows you to enter information about your upcoming trip abroad so that the Department of State can better assist you in an emergency.

Travel Alerts through Concur

If you are using an international mobile phone, enter the phone number on your Concur profile and enable safety and business text message alerts. These alerts will also arrive via email to the verified email addresses on your profile.

Technology Travel Safety

If you plan to travel internationally with a laptop, mobile device, phone, or other computer equipment, please refer to Princeton’s Technology Guidelines for information about keeping your information safe. Instead of using your University-issued equipment, OIT has loaner tablets, laptops, and phones available for use and can help you get set up for your trip. Please plan to coordinate with OIT at least 24-48 hours prior to your trip departure.

Health Information

University Health Services offers pre-travel planning, immunizations, travel-related prescriptions, education, and post-travel evaluation of medical conditions acquired abroad. The Centers for Disease Control and Prevention travelers’ health website provides country-specific information about vaccines and medications you may need before and during your international travel.
