  • The student must not have exceeded 90 days of unemployment in the initial 12-month period of OPT.

A student authorized for a 17-month extension must work at least 20 hours per week for an E-Verify employer in a position directly related to his or her DHS-approved STEM CIP.

For a student who is on a 17-month extension, this employment may include

Multiple employers. A student may work for more than one employer, but all employment must be related to his or her degree program and all employers must be enrolled in E-Verify.

Work for hire. This is also commonly referred to as 1099 employment, where an individual performs a service based on a contractual relationship rather than an employment relationship. The company for whom the student is providing services must be registered with E-Verify. If requested by DHS, the student must be prepared to provide evidence showing the duration of the contract period and the name and address of the contracting company.

Self-employed business owner. A student on a 17-month extension can start a business and be self-employed. In this situation, the student must register his or her business with E-Verify and work full time. The student must be able to prove that he or she has the proper business licenses and is actively engaged in a business related to his or her degree program.

Employment through an agency or consulting firm. A student on a 17-month extension may be employed by an employment agency or consulting firm. The employment agency or consulting firm must be registered with E-Verify, but the third parties contracting with the agency or firm (for which the student is providing services) need not be.

Volunteer work is allowed, but does not count as employment for the purpose of maintaining F-1 status.

Students can work multiple jobs during an OPT STEM extension, but all the employers must be enrolled in E-Verify.

Student Eligibility Requirements:

To be eligible for a STEM extension, you must meet ALL of the following requirements:

  • Completed a degree in a qualifying STEM program (students on pre-completion OPT are not eligible)
  • Currently engaging in PCPT and working with an employer who is currently registered and in good standing with the USCIS E-Verify program
  • Maintaining valid F-1 status
  • Have not accumulated more than 90 days of unemployment
  • Have not previously received a STEM extension
  • USCIS must receive STEM extension application before the expiration date of student's current EAD, but no earlier than 120 days before the expiration date. USCIS recommends that students apply within 90 and 120 days of the expiration date of the current OPT. Timely applications will automatically extend the 12-month OPT work authorization up to 180 days until students receive the 17-month OPT Extension EAD.

What is E-Verify

E-Verify is an Internet based system operated by the Department of Homeland Security (DHS) in partnership with the Social Security Administration (SSA) that allows participating employers to electronically verify the employment eligibility of their newly hired employees. A list of employers who have self-reported participation in E-Verify is maintained by USCIS but students are advised to confirm with employers directly regarding eligiblity. An employer's participation in E-Verify is voluntary and is currently free to employers.

U.S. Citizenship and Immigration Services (USCIS) has just launched the new E-Verify Employers Search Tool which allows students to find employers currently enrolled in E-Verify.
