Our office will not shorten the text you provide so that it fits into the allotted space.

Notes about the Form I-983

Section 1: You will only check “yes” for the question based on a prior degree IF you are applying for the extension based on a degree that was not your most recently earned degree and it was in a STEM field.

Example: You completed an undergraduate degree in engineering followed by a master’s in business administration. You are eligible to apply for a STEM OPT extension based on the engineering degree only if you are currently serving traditional OPT after having completed your MBA. The conditions that apply are located on the studyinthestates website.

If you check yes and earned the prior degree at a U.S. institution, you will need:

  • The school’s name as it appears in SEVIS
  • The SEVIS school code
  • Evidence that the institution that granted it is currently accredited by the U.S. Department of Education
  • Evidence that the same institution is certified by SEVP
  • An official transcript from that institution and a copy of the diploma to submit with your petition

The requested dates in this case are 10/01/20XX-09/30/20XX.

Section 3: Employer information – The start date of employment refers to the next day after the expiration date of your EAD card, not the date on which you began working for your employer.
