It explains the major nonimmigrant work visa categories (H-1B specialty occupation, L-1 intracompany transfer, O-1 extraordinary ability, P performers, E treaty trader/investor, TN NAFTA professionals, R-1 religious worker, J-1 exchange visitor) and immigrant employment categories (EB-1 through EB-5), eligibility requirements, processing, and prepares your case.

How Vikk AI Helps With Your Work Visa Case
Real Walkthrough:How a Software Engineer Successfully Obtained H-1B Visa Through F-1 to H-1B Transition
A software engineer from India completed her Master's degree in Computer Science at a U.S. university. She had been working on F-1 OPT (Optional Practical Training) for 1 year. Her employer wanted to sponsor her for H-1B visa to continue employment. She used Vikk AI to evaluate strategy and timeline.
Step 1: F-1 OPT and STEM extension
After graduation, F-1 student received 12 months of OPT employment authorization. Her employer was E-Verify enrolled, allowing 24-month STEM extension after initial OPT (because Master's degree was in STEM field). Total potential F-1 work authorization: 36 months.
Step 2: H-1B registration
Employer registered her for H-1B in March (during the registration window). Submitted basic information and $10 USCIS registration fee. USCIS conducted lottery in late March. She was selected (advanced degree pool, slightly better chances than general).
Step 3: H-1B petition filing
Employer filed Form I-129 H-1B petition with comprehensive supporting documentation: Labor Condition Application (LCA) approved by DOL, employer's company information, beneficiary's qualifications (Master's degree evaluation, employment history), specialty occupation analysis, prevailing wage determination. $7,250 in USCIS fees (varies by employer size). Filed in April for October 1 start date.
Step 4: H-1B approval and cap-gap
H-1B petition approved within 6 months (used premium processing for $2,805 to expedite). Approved with start date of October 1. Cap-gap protection extended F-1 OPT until October 1 since OPT would have otherwise expired. Smooth transition from F-1 OPT to H-1B status without status gap.
Step 5: Subsequent green card sponsorship
After 1 year on H-1B, employer began green card sponsorship process. PERM filed (12 months process). I-140 filed after PERM approval (4 months process). Priority date established. Because of India's substantial EB-2/EB-3 backlogs, beneficiary remained on H-1B with renewals while waiting for priority date to become current. H-1B can be extended beyond 6 years while green card pending.
Total time: 6 months for H-1B (lottery to approval). Total cost: $7,250 USCIS fees plus $2,805 premium processing plus attorney fees. The case demonstrates several key work visa principles: (1) F-1 to H-1B transition is common path for U.S.-educated students, (2) lottery selection introduces uncertainty, (3) premium processing allows expedited decisions, (4) cap-gap protection bridges status gaps, (5) green card sponsorship can begin during H-1B status with priority date wait.
