Summer 2026 update: International travel risks remain high due to increased federal vetting, travel bans, and unpredictable visa processing. Review the ISSO Travel Decision Guide, ISSO news updates and consult your ISSO advisor to assess your individual risk.

Travel is discouraged if you do not have a valid U.S. visa. Visa appointments are limited, must be completed in your country of citizenship or residence, and delays are common. If you plan to travel and assume the risk, secure a visa appointment before you leave the U.S. and allow at least 30 days for visa processing.

Key Factors to Consider When Planning International Travel

  • Do you have the necessary immigration documentation to return to the U.S.?
    • Do you need a travel signature on your I-20 or DS-2019? See details below.
    • Do you have a valid U.S. visa?
      • If not, can you obtain a new visa in time to return before the start of the next term?
      • If not, are you a national of a country under a U.S. entry/travel ban?
  • Are there other current or political events (military conflicts or sanctions) that could impact your ability to travel and/or obtain a visa? For example:
    • Considerations with a change in federal administration.
    • Consular posts can close without advance notice due to natural disasters or political conflicts
    • Some researchers from China are still experiencing visa denials and visa revocations due to Presidential Proclamation 100043
    • Even with a valid visa, some travelers are denied entry to the U.S. port of entry due to U.S. political sanctions on businesses and nationals of other countries

It is important that you asses your individual situation and evaluate possible risks when making travels plans in the middle of your academic activities. While family emergencies could necessitate travel in the middle of your program, you might choose to postpone some vacation or professional-related travel until after program completion.
