As with many other policies relating to COVID-19, travel guidance may change from time to time in alignment with federal, state and university policies. 

Permissible Travel Guidelines

Restrictions on travel remain one of the key measures available for protecting ourselves and the community as a whole. The risks and uncertainties of traveling domestically and internationally remain. While we continue to recognize our community’s need to remain connected to the broader world of research and learning opportunities, we continue to face substantial obstacles: the risks of bringing infection back to our campus or into the communities we visit; the widely varying governmental responses to the pandemic across the world that severely restrict the logistics of travel; and the potentially insurmountable challenges of supporting our travelers in an emergency.
University-sponsored international and domestic travel remains suspended through the summer with a very limited set of exceptions. The revised Social Contract for undergraduates also directly sets other, stricter limits on travel by those who are subject to its terms, including a general prohibition on any travel – including personal travel – outside New Jersey, Pennsylvania, and New York state, except under a small number of circumstances. Undergraduates must request permission from their college dean or director of student life to be able to travel outside New Jersey, Pennsylvania and New York state.

All University affiliates must register the details of University-sponsored trips to any destination, as well as their contact information, with GS&S prior to departure.

Undergraduate students participating in the testing protocol for campus access during the summer are required to enroll the details of all overnight personal travel and travel of any duration outside of New Jersey, Pennsylvania and New York state. This is in addition to the requirement to obtain permission from their DSL.

All other university affiliates are strongly encouraged to consult and follow the latest guidance from the Centers for Disease Control and Prevention and the U.S. Department of State regarding their personal travel.

You can find the full set of currently applicable domestic and international travel guidelines for the Princeton University community (including registering personal travel) on the International Princeton Travel Toolkit page.The Global Safety & Security unit, reachable via email at, is happy to answer questions related to the permissible travel guidelines.

Travel Outside New Jersey and Potential Quarantine for Faculty, Staff and Students

Post-Domestic Travel Restrictions Lifted May 17, 2021

As of May 17, 2021, New Jersey's travel advisory is no longer in effect. The COVID Risk Assessment Form should now only be completed by individuals (faculty, staff or students) returning from international travel who are not fully vaccinated.

You do not need to complete a COVID Risk Assessment Form and are clear to return to campus without quarantine after travel if:

  • You are arriving to New Jersey after domestic travel, or:
  • You are arriving to New Jersey after international travel and you are fully vaccinated (your travel occurred at least 14 days after your final FDA Authorized or WHO Emergency Use Listed COVID vaccine dose).

You should still follow travel guidance from the NJ Department of Health and all University public health guidelines.

See the NJ self-quarantine for travelers FAQ for more information.

Travel-related Quarantine

Our travel-related quarantine guidelines default to a full 10 day quarantine when quarantine is mandated due either to travel or exposure to an individual that may potentially be infected with COVID. Fully-vaccinated people no longer need to quarantine after domestic travel (see update in section below).

For employees: if you travel to a restricted country and then have to self-quarantine and cannot work from home, you are required to use COVID-19 days, followed by other paid leave including sick, vacation, personal, and/or bundled time.  

Testing for the Purposes of Travel


Some airlines require documentation of a negative test for COVID-19. The University is not offering pre-travel testing to employees and you should not rely upon the asymptomatic testing program for this purpose.

For testing sites, please see these lists for New Jersey, Pennsylvania and New York.

Graduate and Undergraduate Students

Undergraduate and graduate students who are part of the asymptomatic testing protocol can use their results for the purposes of travel. Please note: we cannot guarantee turnaround time for results, and are not able to prioritize individuals’ requests for results.

Students who are not part of the asymptomatic protocol should look to local testing sites for testing required for travel.
