How to use this calculator well

  1. Set your current OPT salary honestly — recruiters' offer letter figures.
  2. Annual raise assumption: 10% reflects typical first-3-years raises for STEM talent; higher if you job-hop.
  3. Major category affects the post-extension salary band assumptions.
  4. Don't skip the H-1B lottery probability — STEM extension is most valuable when there's a realistic shot at H-1B.

Frequently asked questions

Is my major eligible?

Check the CIP code on the STEM Designated Degree Program List (icef.gov). Most engineering, CS, math, statistics, biology, chemistry are. Behavioral economics, finance, marketing are NOT.

Do I have to apply early?

USCIS recommends applying 90-100 days before current EAD expires. Don't pay the premium processing fee unless you're truly late.

Can STEM extension be revoked?

Yes — if you fail to report employer changes every 6 months, fail to do the I-983 validation, or your employer doesn't meet E-Verify requirements.
