O-1 Extensions or Amendments

Current O-1 visa holders need to apply for O-1 extensions in advance of their expiration. The Office of International Student and Scholar Services (OISS) only accepts O-1 requests from Northwestern sponsoring departments. The host department will collect information from the prospective O-1 and provide all of the documents to OISS in one file. The OISS advisor will then review the documents and will work with an immigration attorney, the department, and the prospective O-1 beneficiary to file the petition to U.S. Citizenship and Immigration Services (USCIS).

The type of extension filed may vary slightly but the basic procedures are the same:  

  • O-1 COE (Change of Employer) holds an O-1 at another institution but will be hired by Northwestern.
  • O-1 EOS (Extension) hold an O-1 at Northwestern but will extend employment end-date
  • O-1 Amend holds an O-1 at Northwestern but need to change details such as site of activity, job title, job description, salary, or hours worked

Instructions for O-1 beneficiaries
