Executive Summary: Post-Study Work Authorization

Post-graduation work authorization in the United States is structured under Optional Practical Training (OPT), administered by US Citizenship and Immigration Services (USCIS).

For Indian STEM graduates (Computer Science, Data Science, Engineering, MIS), OPT is the primary mechanism to gain full-time employment at top US technology firms and pay off education loans (US Education Loans Guide).

Here is what Indian families need to know upfront:

  1. 12 Months Initial OPT + 24 Months STEM Extension: All international graduates receive 12 months of initial OPT. STEM-certified degree graduates (STEM OPT Designated MS Cs) receive an additional 24-month extension, providing 36 months (3 full years) of total US work authorization.
  2. Unemployment Allowance Limits: F-1 students on initial 12-month OPT are allowed a maximum cumulative limit of 90 days of unemployment. Securing a STEM extension grants an additional 60 days of unemployment allowance, totaling 150 days across the 36-month period.
  3. E-Verify Employer Requirement for STEM Extension: While initial OPT allows working for any employer related to your degree field, your employer MUST be enrolled in the federal E-Verify Program to qualify for the 24-month STEM extension.

Form I-983 Training Plan & E-Verify Requirements

To apply for your 24-month STEM OPT extension, you and your employer must complete Form I-983 (Mentoring and Training Plan for STEM OPT Students):

  • What Form I-983 Verifies: Details your job duties, specific STEM learning objectives, supervisor evaluation timeline, and confirmation that your salary matches US citizen workers in similar roles.
  • E-Verify Number: Your hiring manager must provide their company's official 7-digit E-Verify Company Identification Number to include in your USCIS application.
