US Visa & Immigration Rules

Demystifying complex US Citizenship and Immigration Services (USCIS) regulations for professionals, students, and family immigrants.

Core Immigration Framework

💼 H-1B Specialty Occupation Rules

The H-1B is the primary work visa for foreign professionals under INA § 101(a)(15)(H)(i)(b). USCIS enforces a strict annual statutory cap of 85,000 visas (65,000 regular cap + 20,000 Master's cap). Under 8 CFR § 214.1(l)(2), workers whose employment ends receive a 60-day grace period to find a new employer or change status.

🎓 F-1 Student OPT & STEM Extension Rules

F-1 students receive 12 months of post-completion Optional Practical Training (OPT). Qualifying STEM degree holders can extend their work authorization by 24 months (36 months total). Under IRC § 3121(b)(19), F-1 OPT students are exempt from FICA Social Security and Medicare taxes.

📁 Green Card Backlogs & Priority Dates

Per-country statutory limits (INA § 202(a)(2) 7% cap) create multi-year backlogs for born-in-India and born-in-China applicants. Applicants monitor the monthly Department of State Visa Bulletin to file Form I-485 when their Priority Date becomes current.

Frequently Asked Questions (FAQ)

Under INA § 214(g)(1)(A), USCIS enforces an annual statutory limit of 85,000 H-1B visas: 65,000 for the regular cap and an additional 20,000 advanced degree exemption cap for applicants with a U.S. Master's degree or higher.

If an H-1B worker's employment terminates prior to their I-94 expiration date, USCIS grants up to 60 consecutive days (or until the end of the authorized I-94 period, whichever is shorter) to find a new employer, change status, or depart the U.S.

F-1 graduates receive 12 months of standard Optional Practical Training (OPT). Qualifying STEM degree holders are eligible for a 24-month STEM OPT extension, allowing up to 36 cumulative months of U.S. work authorization.

Yes. Under Internal Revenue Code (IRC) § 3121(b)(19), F-1 students on approved OPT/CPT are exempt from Social Security and Medicare (FICA) taxes during their first 5 calendar years in nonimmigrant status.

Your Priority Date is the date your PERM (Form ETA-9089) or Form I-140 was filed. The Final Action Date is the monthly Department of State Visa Bulletin cutoff date. You can only file Form I-485 when your Priority Date is earlier than the Final Action Date.

Under 8 CFR § 214.2(f)(10)(i)(A), completing 12 months (365 days) or more of full-time Curricular Practical Training (CPT) automatically forfeits your eligibility for Optional Practical Training (OPT).
