Understand the difference, check if your employer qualifies as cap-exempt, and see which organizations are covered.
Congress limits the number of new H1B visas to 85,000 per fiscal year: 65,000 for the general cap and 20,000 for US master's degree holders. When demand exceeds supply — which has been the case every year since 2014 — USCIS conducts a random lottery in April. In recent years, lottery selection rates have dropped to 20–30%, meaning 70–80% of qualified applicants are simply rejected by random chance.
Cap-exempt employers are carved out of this limitation by statute. They can file H1B petitions year-round, any number of them, with no lottery. An H1B approved through a cap-exempt employer is fully valid — the same legal status as a cap-subject H1B — but required none of the lottery luck. For workers who have been rejected multiple years running, cap-exempt employers are often the only viable path to getting an H1B.
| Factor | Cap-Subject | Cap-Exempt |
|---|---|---|
| Annual Cap | 85,000/year (65K regular + 20K US master's) | No cap — file anytime, unlimited numbers |
| Lottery | Required — random selection if oversubscribed | No lottery — petition decided on merits |
| Registration / Filing Period | March registration window (USCIS opens ~March 1) | File anytime throughout the year |
| Earliest Start Date | October 1 of the fiscal year | Can start as soon as petition is approved (or receipt date with premium) |
| Transfer to Cap-Subject Employer | N/A (already cap-subject) | Moving from exempt to cap-subject employer re-triggers cap — must go through lottery or have prior cap-subject approval counted |
| Prior Cap-Subject Counting | Prior cap-subject counts toward 6-year limit | Cap-exempt time does NOT count toward the 6-year cap period |
| Prevailing Wage / LCA Required | Yes — LCA for every position/location | Yes — same wage and LCA requirements apply |
| Specialty Occupation Test | Yes — same 4-prong test applies | Yes — same specialty occupation test applies |
| Premium Processing | Available ($2,805 for 15 business day action) | Available on same terms |
| Example Employers | Google, Amazon, Infosys, Tata Consultancy, Accenture | Harvard, NIH, UC System, Mayo Clinic (IHE-affiliated), Argonne National Lab |
Cap-exempt employers typically pay less than large tech companies, but the tradeoff is visa certainty — no lottery, no annual uncertainty. Salary ranges vary significantly by sector. All cap-exempt employers must still meet DOL prevailing wage requirements.
| Sector | Typical Role | Salary Range | Notes |
|---|---|---|---|
| Research University (IHE) | Research Scientist / Post-Doc | $65,000 – $110,000 | Lower than industry but strong benefits, visa certainty |
| University Hospital (IHE-Affiliated) | Clinical Researcher / Physician | $90,000 – $220,000 | Clinical roles at top end; research roles lower |
| NIH / Federal Research Agency | Research Fellow / Staff Scientist | $70,000 – $140,000 | GS pay scale; predictable increases, strong job security |
| DOE National Lab | Research Engineer / Scientist | $85,000 – $165,000 | Competitive with industry for mid-level; may require security clearance |
| Nonprofit Research Institute | Data Scientist / Engineer | $80,000 – $135,000 | Varies widely; some institutes match industry rates |
| Cap-Subject Tech (FAANG) | Software Engineer / PM | $140,000 – $350,000+ | Far higher compensation but requires winning lottery |
The DOL iFlag / LCA database shows every H1B filing by employer. Filter for universities, nonprofits, and research organizations. This is the most accurate list of cap-exempt employers actively sponsoring H1B workers.
https://www.dol.gov/agencies/eta/foreign-laborUSCIS publishes detailed guidance on qualifying cap-exempt employers. Review USCIS.gov for the current definition of qualifying IHEs and research organizations to validate employer eligibility.
https://www.uscis.gov/working-in-the-united-states/temporary-workers/h-1b-specialty-occupationsMajor hospital systems affiliated with medical schools (e.g., Mass General/Harvard, UCSF, Johns Hopkins Hospital) are cap-exempt. These are large employers with high H1B sponsorship rates across clinical and tech roles.
Filter LinkedIn job search to include university names, government agencies (NIH, NASA, CDC), and terms like 'H1B sponsorship available' on IHE employer pages.
Many universities have H1B FAQs on their HR websites. Some list the types of positions they sponsor. Staff, IT, research, and administrative roles are all eligible at IHEs.
Moving from a cap-exempt employer to a cap-subject employer is one of the most misunderstood aspects of H1B status. When you transfer to a cap-subject employer, you re-enter the cap — meaning you must either win the lottery or have a previously counted cap-subject approval that you can port.
You can transfer directly to any cap-subject employer under H1B portability. No lottery required. Your prior cap-subject count is preserved indefinitely as long as you maintain H1B status.
You must enter the cap lottery to work for a cap-subject employer. File registration in March and hope for selection. Cap-exempt time gives you no bypass.
Cap-exempt H1B time does NOT count toward the 6-year maximum. You could spend 10 years at a cap-exempt employer and still get 6 full years when you move to a cap-subject employer.
Cap-exempt employers can sponsor you for PERM/I-140 green card petitions just like cap-subject employers. Many universities and research organizations have robust immigration support programs.
