Side-by-side comparison
EB-1A is first-preference; EB-2 NIW is second-preference. EB-1A has a higher evidentiary standard (extraordinary ability) but faster Visa Bulletin movement; EB-2 NIW has a lower bar (advanced degree plus Dhanasar three-prong) but slower bulletin movement, especially for India and China.
- Standard — EB-1A: extraordinary ability with sustained acclaim. EB-2 NIW: advanced degree plus Dhanasar three-prong.
- Degree requirement — EB-1A: none. EB-2 NIW: U.S. master's or foreign equivalent, or U.S. bachelor's plus five years of progressive experience.
- Self-petition — Both yes. No employer or PERM required.
- Premium processing — EB-1A: 15 business days. EB-2 NIW: 45 calendar days.
- Visa Bulletin (worldwide) — EB-1: typically current. EB-2: typically near-current.
- Visa Bulletin (India) — EB-1: a few years backlog. EB-2: over a decade backlog.
- Visa Bulletin (China) — EB-1: a few years backlog. EB-2: multi-year backlog.
When to file EB-1A only
Petitioners with strong sustained-acclaim evidence (international awards, substantial citation impact, high-profile critical roles, top-tier conference papers, recognized media coverage) often file EB-1A only. The category's higher bar is offset by faster processing and the much shorter EB-1 backlog for India and China.
When to file EB-2 NIW only
Petitioners whose record clearly fits the Dhanasar three-prong framework (advanced degree, well-defined nationally-important endeavor, well-positioned to advance it) but does not yet support sustained-acclaim claims usually file EB-2 NIW only.
When to file both in parallel
Many petitioners with borderline EB-1A evidence file both petitions. The two are independent — approval of one does not affect the other. India- and China-born petitioners particularly benefit from this strategy because the EB-2 priority date provides a backup retention pathway if EB-1A is denied.
