For Stanford Travelers


Due to the ongoing surge in COVID-19 in the United States and the world, Stanford recommends delaying travel especially if you are not fully vaccinated.

Fully vaccinated faculty, staff, postdocs, and graduate students are permitted to travel domestically and internationally. Unvaccinated persons who wish to travel internationally must first receive a travel exception from the university (detailed below). Such permission is unlikely to be granted for unvaccinated international travelers during Fall 2021.

Regardless of vaccination status, individuals are required to comply with campus access restrictions and testing requirements following personal or university-sponsored international travel. This includes remaining off campus or quarantining if residing on campus until they submit a negative COVID-19 PCR or Color/LAMP test taken no sooner than 5 days after arriving in California following international travel.

Prior to commencing any travel, individuals must report their vaccination status to the university as described below.

As with all policies during the COVID-19 pandemic, this guidance is subject to changing global health conditions.

On this page, you will find travel guidance, what to do when you return to Stanford from travel and links to frequently asked questions about business travel, cancellations and reimbursements.

Faculty, staff, postdoctoral scholars and students booking air fare, hotels, or rental cars  for university-sponsored travel must utilize a Stanford Travel booking channel in order to ensure reimbursement.

Pre-travel and post-arrival testing and quarantine requirements are continually changing at the local, national and international level. Travelers are strongly advised to verify travel requirements through the Centers for Disease Control or by contacting Stanford’s Global Risk office.

Current status

As of September 21

Effective September 20, 2021

Following CDC, state, and county guidance, Stanford University is updating its travel guidance as a result of factors including the widespread emergence of the COVID Delta variant. Travelers at schools or programs with more restrictive policies will be required to follow those more restrictive policies.

While fully vaccinated travelers are at less risk to themselves and others, unvaccinated travelers and those who are not fully vaccinated (collectively referred to here as “unvaccinated travelers”) are at even greater risk of contracting the Delta variant and spreading it to others than with previous strains.

Stanford will permit international travel ONLY for fully vaccinated individuals, subject to conditions determined by the nature of the travel, activity, and traveler’s role at the university. Travelers must upload proof of COVID-19 vaccination prior to departure. Faculty, staff and postdocs must upload proof of vaccination status using Health Check. Graduate and undergraduate students must upload proof of vaccination documentation to the VadenPatient portal. All students also must attest to their vaccination status in the Health Check system.


Fully Vaccinated Travelers 

Fully vaccinated faculty, staff, postdocs, and graduate students are permitted to travel both domestically and internationally without requesting an exception. However, field research that involves clinical or non-clinical human subjects continues to require prior approval.

Unvaccinated Travelers

Unvaccinated faculty, staff, postdocs and graduate students may travel domestically without a travel exception. Those who are unvaccinated and have a critical and essential need to travel internationally on university business must be approved for a travel exception prior to commencing travel. Critical and essential travel is defined as:

  • Advancing critical research in the national or global interest.
  • Preserving the continuity of research that cannot be repeated, replaced, performed remotely, or by another fully vaccinated Stanford traveler or proxy, and that is necessary to preserve the safety/well-being of research subjects.
  • Supporting a critical Stanford research, educational, or administrative/operational function that cannot be deferred, accomplished remotely, or performed by a fully-vaccinated Stanford traveler.
  • Maintaining progress toward academic degree and that cannot be postponed, replaced, or accomplished remotely or by proxy

Given current COVID-19 conditions, as well as federal and local guidelines, the university is unlikely to grant unvaccinated travelers permission for international travel in Fall 2021. 

Travel exceptions should be requested at least 4 weeks in advance of the date a decision is needed. Unvaccinated international travelers must have a travel exception prior to departure in order to be reimbursed for international trips.


Beginning September 20, 2021, undergraduates may travel for Stanford-related course field trips and field research within California. All such travel must be accompanied by an instructor or staff member. International travel and domestic travel outside California continues to be not permitted. Course-related travel has additional requirements found here.

Bing Overseas Studies Program (including SiNY) and Stanford in Washington

Travel associated with the Bing Overseas Studies Program (BOSP), Stanford in New York, and Stanford in Washington will be permitted for fully vaccinated undergraduates. Unvaccinated students who wish to participate in BOSP programs both abroad and in New York, or in Stanford in Washington, must begin the vaccination exception request process for travelers at least 4 weeks in advance of the program withdrawal deadline. Given current COVID-19 conditions, permission for travel through Bing Overseas Studies Program or Stanford in Washington is unlikely to be granted to unvaccinated undergraduate students in Fall 2021 and Winter 2022. For Stanford in Washington, internships and many learning opportunities will not be available to unvaccinated students.  Approval for vaccine exemption for on-campus enrollment does not automatically extend to off-campus programs. For more information about program specific withdrawal deadlines please see the BOSP Participation Agreement.


At this time, the University is advising academic departments and programs that offer study abroad and international educational learning opportunities to plan their full course of activities for vaccinated students for Spring and Summer of 2022. The University already is working closely with campus partners to plan for Spring and Summer 2022, and to develop contingency plans should COVID conditions deteriorate.



Travelers may benefit from global travel risk assessments and mitigation recommendations. This service is available through the Global Risk office ( and is particularly useful for:

(1) Travel to higher-risk destinations (based on information from the U.S. Department of State, Centers for Disease Control, International SOS or other reliable sources of information for health, safety or security risks),

(2) Group trips that include five or more travelers, and,

(3) Travelers with particular vulnerabilities.
