After Hours Contact

The Office of International Student and Scholar Services’ After-Hours Contact is the university’s official response to recent federal regulations impacting travel by international students, scholars, and their dependents. Any one of these individuals who may be experiencing one of the following situations may contact the OISS After-Hours Contact:

  1. If you are denied boarding a flight bound to the U.S., or denied entry into the U.S., where all of your immigration documentation is valid and are a current student, scholar, or dependent; or
  2. If you are detained at an airport or a U.S. Port of Entry (e.g. border-crossing, seaport, etc.)

The OISS After-Hours Contact phone number is the Northwestern University Police Department (NUPD): 1-847-491-3456 (from abroad: 001-847-491-3456)

Please note the exceptions to calling this number below: 

  • If you forgot or lost your immigration documents (DS-2019, I-20, EAD card, Approval Notice, etc.), do not call the number. Instead, email your OISS advisor for assistance.
  • If your visa application is delayed or denied, do not call the number. Instead, email your OISS advisor for assistance.
  • If you are currently in Evanston/Chicago, do not call the number. Instead, email your OISS advisor or come to the OISS during business hours.
  • If Northwestern does not sponsor your immigration status, do not call the number. Instead, contact your immigration sponsor for assistance. (Example: Fulbright, F-1 OPT or J-1 AT through another institution, etc.)
  • If you are in the U.S. and hurt or in danger, do not call this number. Instead, call 911. If you are overseas call emergency services in that country.

If you have an urgent situation that may make international travel seem necessary (e.g. for family emergency), please contact the Office of International Student and Scholar Services immediately so we can arrange a consultation with an immigration attorney who can further assess the risks associated with your travel abroad for your return to the U.S.

The Office of International Student and Scholar Services is open Monday – Friday, from 8:30am-5:00pm, and can be reached via: 847-491-5613.
