E-Verify
E-Verify is an electronic employment eligibility verification system under which employers commit to use an electronic database to check whether the name and social security number presented by new hires match the records in the Social Security database, and whether any immigration documents presented by the employee match information in Department of Homeland Security database. If an employer is not enrolled in E-Verify, a STEM student can NOT obtain a 17 month OPT extension. More information on E-Verify is available at the USCIS website.
Application
You may file for the 17-month STEM extension up to 120 days prior to the end of your post-completion OPT. You will submit your application for the 17-month OPT Extension to the Davis International Center.
Checklist and Application PROCESS
Student Reporting Requirements
1. You are still in F-1 status while on STEM OPT extension, and under Princeton University's visa sponsorship, so you must continue reporting any changes of address to the Davis International Center within 10 days of change. Please report address changes, name changes, employment updates, employment interruptions and loss of employment by submitting the OPT Address/Employer Change Form. You can also send these reports to your international student advisor directly.
2. You must also send to the Davis International Center a validation report every six months starting from the date of STEM extension starts and ending when your F-1 status ends or the STEM extension ends, whichever comes first. The validation report must include your:
- First and last names
- SEVIS ID number
- Current U.S. living address
- Name and address your current employer, and
- Date you began working for the current employer.
The report must be submitted to through the OPT and STEM OPT Reporting Form within 10 days of each 6 month reporting period.
Please note that, if this report is not submitted and your SEVIS record is not updated every six months, your SEVIS record will be automatically terminated and you will no longer have valid immigration status in the U.S.
Employer Reporting Requirements
The employer must report to the Davis International Center within 48 hours when the job ends or the student leaves the employer. Employers should seek guidance about this from their legal counsel or directly from Immigration.
Periods of Unemployment While on OPT
Maintaining F-1 status during OPT and STEM OPT requires that a student is employed for at least 9 of 12 months during the initial 12 months of OPT, and at least 25 of 29 months during the entire 29 month OPT/STEM OPT period. Each day (including weekends) during the period when OPT/STEM OPT authorizations begin and end that the student does not have qualifying employment counts as a day of unemployment. STEM OPT authorization beings one day after initial 12 months of OPT end.
For student reaching the limit of unemployment time, the Student and Exchange Visitor Program (SEVP) suggests that, "prior to reaching the limit on authorized unemployment the student should prepare to transfer to another SEVP-certified school, change educational level, depart the United States, or take action to otherwise maintain status in the United States" (SEVP Policy Guidance, page 22).
The SEVP Guidance also states that "a student who has exceeded the period of unemployment while on post-completion OPT has violated his or her status unless he or she has taken one of the following actions:
- Applied to continue his or her education by a change of education level or transferring to another SEVP-certified school
- Departed the United States
- Taken action to otherwise maintain legal status"
Travel
You remain in F-1 status and under Princeton visa sponsorship until the end of your entire OPT/STEM OPT period. When traveling outside the U.S., you must carry your I-20 with a valid travel signature (obtained within the last 6 months), proof of work authorization (EAD card) and an employment letter stating the job title, job description, beginning/end dates, and salary. If your F-1 visa has expired, you will need to apply for a new visa before returning to the U.S. Students who need a new entry visa are strongly advised to consult with their international student ad visor before making travel plans.
