US skilled worker immigration is for professionals, skilled workers and workers with a job offer in the United States. In 2025, the US issues ~140,000 Employment-Based Green Cards annually, divided into 5 categories from EB-1 to EB-5. This article summarizes 6 pathways for US skilled worker immigration most feasible for Vietnamese applicants — with conditions, timelines and costs.
What is US skilled worker immigration?
US skilled worker immigration (Employment-Based Immigration) is a group of visas granting US permanent residency (Green Card) based on professional ability. Unlike family-based or refugee categories, the skilled worker category prioritizes people with high education, special skills, or financial investment.
There are 5 main categories (EB-1 to EB-5) plus several work permit categories (H-1B, O-1, L-1) that can convert to a Green Card. The total quota is ~140,000 PRs/year, with each country capped at 7% — Vietnam usually does not face a severe backlog like India or China.
6 pathways for US skilled worker immigration in 2025
1. EB-2 NIW — National Interest Waiver
EB-2 NIW is for professionals with a master’s degree plus an outstanding record in a field that serves the “national interest” of the US. No employer sponsorship required, no job offer letter needed, no PERM Labor Certification required. This is the most popular pathway for startup founders, researchers, and Vietnamese STEM engineers. Read details at EB-2 NIW guide.
2. EB-3 Skilled Worker / Professional
EB-3 is for skilled workers (≥ 2 years of experience), professionals with a bachelor’s degree, and unskilled workers. Requires PERM Labor Certification from a US employer. Details at EB-3 Visa.
3. H-1B Specialty Occupation
H-1B is not a Green Card — it is a 3-year work permit visa (extendable up to 6 years) that can later convert to EB-2/EB-3. Only 85,000 slots are issued each year through a lottery. Details at H-1B Visa 2025.
4. O-1 Extraordinary Ability
O-1 is for people with “extraordinary ability” in science, art, education, business, or athletics. Requires proving ≥ 3 of 8 criteria (awards, publications, judging panel, salary, original contribution…). No cap, processed within 2–4 weeks with premium processing.
5. L-1 Intracompany Transfer
L-1 is for employees of multinational companies transferring from a branch in Vietnam to the US. There are 2 types: L-1A (managers/executives) and L-1B (specialized knowledge). L-1A can convert to an EB-1C Green Card after 1 year.
6. EB-5 Investor Visa
EB-5 is for investors putting ≥ 800,000 USD into a Targeted Employment Area (TEA) or 1,050,000 USD in a standard area, creating ≥ 10 full-time jobs for Americans. Timeline is 36–60 months. Suitable for wealthy families wanting to bring their children along.
