Every launch has a crowd of people behind it: propulsion engineers, guidance specialists, materials scientists, and mission software developers. Many were born somewhere else. They came here because this is where the hardware is being built, and they want to stay because the work isn't done.

I'm David Keller, and my immigration practice focuses on one question: how do people get to where the future is being built? For aerospace professionals, that usually comes down to a few visa categories. Here's a plain-English map.

The O-1A is a temporary (nonimmigrant) classification for people with extraordinary ability in the sciences, education, business, or athletics (INA § 101(a)(15)(O)). To qualify, you generally show either a major internationally recognized award or at least three of the eight evidentiary criteria in 8 CFR 214.2(o)(3)(iii). They include original contributions of major significance, scholarly articles, judging others' work, a critical role at a distinguished organization, and high pay. USCIS then looks at the whole record to decide whether you have sustained national or international acclaim and are among the small percentage at the very top of your field (USCIS Policy Manual, Vol. 2, Part M, Ch. 4).

In January 2025, USCIS updated its O-1 guidance, including examples of evidence for people working in critical and emerging technologies (USCIS Policy Alert PA-2025-02). For aerospace engineers, that can mean patents, publications, peer review, and a leading role on a significant program. An O-1 needs a U.S. employer or agent to petition (8 CFR 214.2(o)(2)), and it is not subject to the H-1B lottery.

EB-1A is the permanent-residence counterpart (INA § 203(b)(1)(A)). You can petition for yourself with no employer and no labor certification (8 CFR 204.5(h)(5)). The evidence is either a one-time major achievement or at least three of the ten criteria in 8 CFR 204.5(h)(3). USCIS then makes a “final merits determination” on whether you have sustained acclaim and are among the small percentage at the top of your field (USCIS Policy Manual, Vol. 6, Part F, Ch. 2). The bar is high, but you own the petition, not your employer.

The EB-2 National Interest Waiver lets an advanced-degree professional or a person of exceptional ability skip the job offer and labor certification (INA § 203(b)(2)(B)). Here's what I love telling engineers: the leading case, Matter of Dhanasar, 26 I&N Dec. 884 (AAO 2016), involved an engineer whose proposed endeavor was research and development on air and space propulsion systems. USCIS's own Policy Manual still uses it as the example (Vol. 6, Part F, Ch. 5).

Dhanasar is still the framework USCIS applies as of October 2026. You must show (1) your proposed endeavor has substantial merit and national importance, (2) you are well positioned to advance it, and (3) on balance, waiving the job offer benefits the United States (USCIS Policy Manual, Vol. 6, Part F, Ch. 5). USCIS updated this guidance in January 2025. The update covers national importance, support letters, and business plans, and it builds on earlier STEM and entrepreneur guidance (USCIS alert, Jan. 15, 2025). The waiver is discretionary, so approval is never automatic.

National importance is about the endeavor's potential impact, not just your résumé. Depending on the facts, aerospace work may connect to national security, communications and navigation infrastructure, Earth observation, advanced manufacturing, or critical and emerging technologies. Specificity matters most: what you plan to build or research, why it matters beyond one employer, and evidence (citations, patents, funding, independent letters) that you can deliver it.

Many engineers start on H-1B. The program has changed a lot. A September 19, 2025 presidential proclamation imposed a $100,000 payment on certain new H-1B petitions, and it was extended in September 2026 (White House). Federal courts have since blocked collection, and USCIS says it is complying while appeals continue (USCIS H-1B page). Separately, DHS has proposed (not finalized) an additional fee for cap-subject petitions (Federal Register, Aug. 25, 2026). A new wage-weighted lottery took effect for the FY 2027 season (Federal Register, Dec. 29, 2025). With rules this fluid, O-1A and self-petitioned green cards deserve a serious look.
