Information about H-1B, TN, E-3 and O-1 status

Maintaining your H-1B, TN, E-3 and O-1 visa status

• Prior to any changes in employment, OIVS must be consulted to determine if an H-1B/TN/E-3/O-1 amendment is required. Changes in employment such as position title, position responsibilities, degree requirements for the position, sponsoring department, work location and number of hours worked must be communicated to OIVS. Failure to notify OIVS prior to a material change in employment may place CHOP and the H-1B/TN/E-3/O-1 employee in violation of immigration rules and regulations.
• For employees continuing in H-1B/TN/E-3/O-1 status, an extension must be properly filed prior to the expiration of their status. Requests for an extension must be submitted in the Service Center by your Manager or Department Representative.
• H-1B/TN/E-3 and O-1 employees are not permitted to accept payment from sources outside of CHOP.
• I-94: All nonimmigrants are issued an I-94 upon each admission to the US. If you are a nonimmigrant, please remember to check your I-94 after each entry to the US through this website. If you are entering via a land border, check your paper I-94 to ensure the information is accurate. Please report any errors on your I-94 immediately to CBP and OIVS. See the FAQ, "What should a traveler do if he or she was admitted incorrectly to the United States?"
• Residential Address Change: Nonimmigrants in H, TN, O-1 and E-3 status must notify USCIS within 10 days of moving. Form AR-11, Change of Address, can be completed online.
• Passports: All nonimmigrants are required to maintain a valid passport. Expiring passports should be renewed as soon as possible, due to potential delays resulting from the COVID-19 pandemic. Please be aware that CBP officers have the discretion to shorten the I-94 admission record to match one's passport expiration date.
