About US H-1B Specialty Occupation Visa
The H-1B is the principal US visa for foreign professionals in specialty occupations requiring at least a bachelor's degree (or equivalent) in a specific field. Annual cap of 65,000 plus 20,000 advanced-degree-from-US holders. The cap is consistently oversubscribed; USCIS conducts an electronic registration / lottery each March for October-1 start dates. Initial validity of 3 years, extendable to 6, with further extensions if green-card process is in progress. The H-1B is the most significant skilled-worker pathway into the US labour market, and the standard route into the EB-2 / EB-3 employment-based green card.
Full US H-1B Specialty Occupation Visa profile →About US TN Visa (Trade NAFTA / USMCA Professional)
The TN (Trade NAFTA) classification, continued under the US-Mexico-Canada Agreement (USMCA) that replaced NAFTA on July 1, 2020, allows citizens of Canada and Mexico working in one of roughly 60 designated professional occupations (Appendix 2 to USMCA Chapter 16, formerly NAFTA Annex 1603 — including accountants, engineers, computer systems analysts, scientists, teachers, and various healthcare professions) to work temporarily in the United States for a US employer. Canadian citizens can apply directly at a US port of entry or a pre-clearance facility with no visa stamp required; Mexican citizens must obtain a TN visa through consular processing (DS-160 plus interview). There is no annual cap and no lottery. TN status is granted in increments of up to 3 years and can be renewed indefinitely, but it is explicitly a non-immigrant, non-dual-intent category — it carries no built-in path to permanent residency, and pursuing a green card while on TN status can complicate renewal or admission if it suggests immigrant intent.
Full US TN Visa (Trade NAFTA / USMCA Professional) profile →Gotchas to Watch For
US H-1B Specialty Occupation Visa
- ⚠The H-1B lottery is a hard constraint — selection rate has hovered around 25% per cycle since FY2024
- ⚠Spouse work authorisation (H-4 EAD) requires principal to be on the employment-based green card path with an approved I-140
- ⚠AC21 portability requires 180+ days post-I-140 approval before changing employers without resetting priority dates
- ⚠Country-of-birth (not citizenship) determines green-card priority date — Indian and Chinese H-1B holders face decade-plus EB-2/EB-3 backlogs
- ⚠Status loss on termination is fast — 60-day grace period only
US TN Visa (Trade NAFTA / USMCA Professional)
- ⚠The USMCA Appendix 2 occupation list is essentially frozen at 1994 NAFTA-era job titles — many in-demand modern roles have no exact match and must be carefully mapped to an analogous listed category, which is a common source of CBP pushback
- ⚠TN is explicitly not a dual-intent visa — evidence of immigrant intent (e.g., a green card application in progress) can jeopardize renewal or re-entry, unlike H-1B or L-1
- ⚠Canadian citizens should not think of TN as a 'visa' in the stamped-document sense — it's a nonimmigrant classification granted at the border with no physical visa required, which also means there's no consular fallback if a CBP officer refuses admission on the spot
- ⚠TD dependents (spouse/children) do not automatically receive work authorization, unlike H-4 or L-2 — a significant disadvantage for accompanying spouses versus H-1B or L-1
- ⚠No cap and no lottery, but also no guaranteed multi-year runway like H-1B's 6-year AC21 extensions — each TN period is tied strictly to the current job and must be justified on its own merits at renewal
- ⚠Only Canadian and Mexican citizens qualify — permanent residents or other nationals of those countries are not eligible, even if they live in Canada or Mexico
