The H-1B1 is a specialty occupation work visa created by the US–Chile and US–Singapore Free Trade Agreements. It covers the same range of degree-required professional roles as the H-1B but operates without a lottery — visas are issued first-come, first-served within an annual cap of 6,800 — and is available exclusively to Chilean and Singaporean nationals.

The H-1B1 is a nonimmigrant specialty occupation visa established by the US–Chile Free Trade Agreement (2004) and the US–Singapore Free Trade Agreement (2004). It functions similarly to the H-1B — requiring a specialty occupation position and a certified Labor Condition Application — but with key structural differences: no annual lottery, 1-year validity periods, and the absence of dual intent. Only Chilean and Singaporean nationals may apply. Unused H-1B1 numbers are added to the general H-1B pool each year if not exhausted, so practical availability has generally been strong. See the official USCIS H-1B1 guidance for current requirements.
H-1B1 is available only to Chilean and Singaporean nationals, issued in 1-year increments (vs. 3 years for H-1B), has no annual lottery, and does not carry dual intent. There is also no premium processing option. In exchange, the absence of a lottery means far more predictable availability — historically, demand has rarely approached either sub-cap. See USCIS H-1B1 guidance.
H-1B1 uses the same specialty occupation standard as H-1B — the position must require at least a bachelor's degree in a specific specialty directly related to job duties. Excluded occupations include disaster relief, religious occupations, and news media roles. Common qualifying fields: software engineering, finance, accounting, architecture, medicine, and engineering. USCIS scrutinizes whether the specific role genuinely requires degree-level specialized knowledge.
Not directly — H-1B1 does not carry dual intent. Workers who wish to pursue an employment-based green card while in H-1B1 status typically need to first transition to H-1B (by going through the lottery or via a cap-exempt employer). Once in H-1B status, they can file I-140 or begin PERM without risk to their nonimmigrant status.
Yes, but H-1B portability does not extend to H-1B1. The new employer must file a new I-129 with a certified LCA before the worker can begin employment — there is no "portability upon filing" provision. Workers and employers should plan employer transitions carefully to avoid unauthorized employment, and should file the new petition as early as possible to minimize any gap.
