The Complete H-1B Visa Guide
Everything you need to know about the H-1B specialty occupation visa, from the basics to advanced strategy. Based on official USCIS data and regulations.
1What is the H-1B Visa?
The H-1B visa is a non-immigrant work visa that allows U.S. employers to temporarily hire foreign workers in specialty occupations—roles that require at minimum a bachelor's degree (or equivalent) in a specific field directly related to the job. Think software engineers, data scientists, architects, accountants, doctors, and university professors.
Duration
3 years initial, extendable to 6 years maximum. Extensions beyond 6 years possible if a green card process is pending.
Employer-Sponsored
You cannot self-petition. A U.S. employer must file the petition on your behalf and offer you a specific job.
Dual Intent
Unlike most non-immigrant visas, H-1B allows dual intent. You can pursue a green card (permanent residence) while on H-1B status.
Dependents
Your spouse and unmarried children under 21 can join you on H-4 visas. Spouses may be eligible for work authorization (H-4 EAD).
The H-1B program was created by the Immigration Act of 1990 and has become the primary pathway for skilled foreign workers to enter the U.S. workforce. In FY2024, USCIS received over 470,000 petitions, making it one of the most sought-after visa categories in the world.
2Key Terms Glossary
Master these terms and you'll be able to follow any H-1B discussion, immigration lawyer consultation, or USCIS document.
- Beneficiary
- The foreign worker who will receive the H-1B visa. That's you (the employee).
- Petitioner
- The U.S. employer who files the H-1B petition on behalf of the beneficiary. They are legally responsible for the petition.
- LCA (Labor Condition Application)
- A form (ETA-9035) filed by the employer with the Department of Labor before the H-1B petition is submitted. The employer attests they will pay the prevailing wage and not adversely affect working conditions of U.S. workers.
- Prevailing Wage
- The average wage paid to similarly employed workers in a specific occupation in the area of intended employment. Set by the DOL based on occupation, location, and skill level (Levels I–IV).
- Specialty Occupation
- A job that requires the theoretical and practical application of a body of highly specialized knowledge and a bachelor's degree or higher in a specific discipline. This is the core eligibility requirement for H-1B.
- Cap-Subject vs. Cap-Exempt
- Cap-subject petitions count toward the annual 85,000 limit and must go through the lottery. Cap-exempt employers (universities, nonprofit research organizations, government research organizations) can file H-1B petitions at any time without being subject to the cap.
- Initial vs. Continuing Employment
- Initial employment is a first-time H-1B. Continuing employment covers extensions, amendments, or changes with the same or a new employer for someone already in H-1B status.
- Premium Processing
- An optional service (Form I-907) where USCIS guarantees a response within 15 business days. Available for an additional fee. The response can be an approval, denial, RFE, or NOID — it guarantees speed, not outcome.
- RFE (Request for Evidence)
- A notice from USCIS asking for additional documentation before they can make a final decision on the petition. Common and not necessarily a bad sign.
- NOID (Notice of Intent to Deny)
- A more serious notice indicating USCIS intends to deny the petition but gives the petitioner a chance to respond. Requires immediate attention.
- I-129 (Petition for a Nonimmigrant Worker)
- The actual form the employer files with USCIS to petition for the H-1B worker. Accompanied by the H-1B data collection supplement and supporting evidence.
- EAD (Employment Authorization Document)
- A work permit. While H-1B workers are authorized to work for their sponsoring employer specifically, EADs provide broader work authorization (relevant for H-4 EAD holders).
- H-4 (Dependent Visa)
- The visa classification for spouses and unmarried children (under 21) of H-1B holders. H-4 holders can live and study in the U.S. but generally cannot work unless they obtain an H-4 EAD.
- H-4 EAD
- Available to H-4 spouses of H-1B workers who are the beneficiary of an approved I-140 (immigrant petition) or who have been granted H-1B extensions beyond the 6-year limit under AC21 sections 104(c) or 106(a).
- Consular Processing vs. Change of Status (COS)
- Consular processing: the worker obtains an H-1B visa stamp at a U.S. embassy/consulate abroad and enters the U.S. Change of status: the worker is already in the U.S. on another valid status and switches to H-1B without leaving the country.
- USCIS / DOS / DOL
- USCIS (U.S. Citizenship and Immigration Services) adjudicates the H-1B petition. DOS (Department of State) handles visa stamping at consulates. DOL (Department of Labor) certifies the LCA and sets prevailing wages.
3The H-1B Process Step by Step
For cap-subject petitions (the majority of new H-1Bs), the process follows this timeline. Cap-exempt and transfer petitions skip the lottery step.
Electronic Registration
March (3 weeks)Employer (or their attorney) submits a $215 electronic registration for each beneficiary during the annual registration window, typically in early-to-mid March.
Lottery Selection
Late March - AprilUSCIS runs the lottery using beneficiary-centric selection (since FY2025). Starting FY2027, selections are weighted by wage level. If selected, you receive a selection notice.
Employer Files LCA with DOL
7-10 business daysThe employer files a Labor Condition Application (ETA-9035) with the Department of Labor, attesting to prevailing wage and working conditions. DOL typically certifies within 7 business days.
Employer Files I-129 with USCIS
Within filing window (90 days)With the certified LCA and selection notice, the employer files Form I-129 (the actual petition) with USCIS. Selected registrants have a 90-day window to file. The petition includes evidence of the specialty occupation, beneficiary qualifications, and employer-employee relationship.
USCIS Adjudication
2-6 months (or 15 business days premium)USCIS reviews the petition. They may approve it outright, issue an RFE requesting more evidence, or deny it. Premium processing guarantees a response within 15 business days.
Visa Stamping or Change of Status
VariesIf approved: workers abroad attend a consular interview to get the H-1B visa stamp, then enter the U.S. Workers already in the U.S. can change status without leaving. H-1B status begins October 1 of the fiscal year.
Start Work
October 1The H-1B worker begins employment on or after October 1. The employer must provide working conditions and pay as stated in the LCA and petition.
4The H-1B Cap & Lottery System
Congress limits the number of new H-1B visas issued each fiscal year. This annual limit, known as the cap, has been a defining feature of the program.
Annual Cap Breakdown
The cap has remained at 65,000 + 20,000 since FY2005 (set by the H-1B Visa Reform Act of 2004). It was temporarily raised to 115,000 (FY1999-2000) and 195,000 (FY2001-2003).
How the Lottery Works
Since demand far exceeds the 85,000 cap, USCIS conducts a lottery (random selection) to determine which petitions can be filed. The system has evolved significantly:
Employers mailed full petition packages. USCIS physically received and randomly selected among them. Costly and wasteful for unselected petitions.
Electronic registration system introduced. Employers submit a simple $10 (now $215) online registration per beneficiary. Only selected registrants file full petitions.
Beneficiary-centric selection. Each unique beneficiary gets one entry regardless of how many employers register them. This eliminated the gaming strategy of filing through multiple companies.
Weighted lottery by DOL wage level. Higher-wage-level positions have higher selection probability. Level IV wages have the highest odds, Level I the lowest. This is a major shift toward prioritizing higher-paid specialty workers.
Registration & Selection Rates
| Fiscal Year | Registrations | Selected | Selection Rate |
|---|---|---|---|
| FY2021 | 274,237 | 124,415 | 45.4% |
| FY2022 | 308,613 | 131,970 | 42.8% |
| FY2023 | 483,927 | 127,600 | 26.4% |
| FY2024 | 758,994 | 188,400 | 24.8% |
| FY2025* | 479,953 | 120,603 | 25.1% |
| FY2026 | 399,781 | 120,516 | 30.1% |
| FY2027 | 397,325 | 120,322 | 30.3% |
* FY2025 was the first year with beneficiary-centric selection, which dramatically reduced duplicate registrations.
Cap-Exempt Employers
Not all employers are subject to the cap. The following can file H-1B petitions at any time of year without going through the lottery:
- Institutions of higher education (universities and colleges)
- Nonprofit entities related to or affiliated with institutions of higher education
- Nonprofit research organizations
- Government research organizations

8Important Policy Changes Timeline
H-1B Program Created
Immigration Act of 1990 establishes the H-1B visa category with an annual cap of 65,000.
ACWIA Passed
American Competitiveness and Workforce Improvement Act raises the cap to 115,000 for FY1999 and FY2000. Introduces ACWIA training fee.
AC21 Act
American Competitiveness in the 21st Century Act raises the cap to 195,000 for FY2001-2003. Introduces H-1B portability (start work on receipt) and exemptions for the 6-year limit if green card process is pending.
Cap Returns + Master's Exemption
H-1B Visa Reform Act of 2004 returns the cap to 65,000 but adds 20,000 additional visas for U.S. master's degree holders (effective FY2005). Introduces $500 fraud prevention fee.
Steady Demand Growth
Cap consistently reached within the first week of filing. USCIS implements lottery system. Demand grows from tech sector expansion.
Heightened Scrutiny Era
"Buy American, Hire American" executive order. Denial rates peak at 24% in FY2018 (up from 6% in FY2015). Massive increase in RFEs. Multiple policy memos tighten standards for IT consulting, entry-level positions, and computer programmers.
Electronic Registration Pilot
USCIS launches electronic registration for the H-1B cap (used starting FY2021), replacing the expensive mail-in paper lottery.
Registration Abuse
Electronic registration's low cost ($10) leads to a surge in multiple registrations per beneficiary. FY2024 sees nearly 759,000 registrations, many duplicative, driving selection rates below 25%.
Major Reforms
USCIS implements beneficiary-centric selection (effective FY2025), new fee schedule including Asylum Program fee, modernization of the H-1B program definition of specialty occupation, and codification of deference to prior approvals.
Record Approval Rate
H-1B approval rate reaches 97.9%, the highest in recent history. Beneficiary-centric selection reduces gaming. Registration fee raised to $215.
Weighted Wage-Based Lottery
The most significant recent change: H-1B lottery selections are weighted by DOL wage level. Higher-wage positions have greater selection probability, shifting the program toward higher-paid specialty workers.
9Common Mistakes & Tips
Quick Reference: Key Deadlines
10Frequently Asked Questions
Can I change employers on an H-1B?
Yes. Your new employer files a new H-1B petition (I-129) on your behalf. Under H-1B portability rules (AC21 section 105), you can start working for the new employer as soon as the petition is received by USCIS, even before approval. You do not need to go through the lottery again if you are already in H-1B status. This is called an H-1B transfer, though technically it is a new petition.
What happens if I am laid off?
You have a 60-day grace period (or until the end of your H-1B validity period, whichever is shorter) to find a new employer to file an H-1B transfer, change to a different valid nonimmigrant status (such as B-1/B-2 or F-1), or depart the United States. Your employer is required to notify USCIS when your employment ends. The 60-day grace period was codified in the 2017 DHS regulations.
Can my spouse work on H-4?
Generally, H-4 visa holders cannot work. However, H-4 spouses can apply for an Employment Authorization Document (H-4 EAD) if the H-1B principal beneficiary has an approved I-140 immigrant petition, or if they have been granted an H-1B extension beyond the 6-year limit under AC21 sections 104(c) or 106(a). The H-4 EAD allows the spouse to work for any employer in any occupation.
What if I am not selected in the H-1B lottery?
You have several options: (1) Try again the following fiscal year, (2) Find a cap-exempt employer (universities, nonprofit research organizations), (3) Explore other visa categories such as O-1 (extraordinary ability), L-1 (intracompany transfer), or TN (for Canadians and Mexicans), (4) Consider enrolling in a degree program and using OPT/CPT, (5) Your employer may have international offices where you can work and try the lottery again.
How long is the green card wait for H-1B workers?
It depends heavily on your country of birth and the visa category. For EB-2 and EB-3 employment-based categories: workers born in India face a backlog estimated at decades (some estimates suggest 50+ years for current applicants). Workers born in China face a backlog of several years. For most other countries, the wait is relatively short (1-3 years for the entire PERM, I-140, I-485 process). The per-country limit of 7% of total annual EB visas is the primary cause of the India and China backlogs.
Can I travel while my H-1B is pending?
If you filed for a change of status (COS) and leave the U.S. while it is pending, your COS request is considered abandoned. If you already have H-1B status and are extending or transferring, you generally can travel, but you will need a valid H-1B visa stamp in your passport to re-enter. If your stamp has expired, you will need to attend a consular interview before returning.
What is the difference between H-1B and H-1B1?
The H-1B1 is a special variant available only to citizens of Singapore and Chile under free trade agreements. It has its own allocation (5,400 for Singapore, 1,400 for Chile, carved out of the 65,000 cap). The process is slightly different: no USCIS petition is required for initial H-1B1 status — the worker applies directly at the consulate. Unused H-1B1 numbers roll back into the regular H-1B cap.
Can I start a company or do freelance work on H-1B?
This is highly complex. You can own a company, but you generally cannot be self-employed on H-1B because the visa requires a valid employer-employee relationship where the employer has the right to control when, where, and how you perform the job. Some immigration attorneys can structure arrangements where you own a company and there is still a qualifying employer-employee relationship, but this requires careful legal guidance.
What counts as a 'specialty occupation'?
A specialty occupation requires the theoretical and practical application of a body of highly specialized knowledge, and attainment of a bachelor's or higher degree (or its equivalent) in the specific specialty as a minimum for entry into the occupation. The 2024 modernization rule clarified that there must be a direct relationship between the degree field and the job duties. Common qualifying occupations include software development, engineering, accounting, architecture, medicine, law, and education.
What happens after 6 years on H-1B?
Generally, you must leave the U.S. for at least one year before being eligible for a new H-1B. However, AC21 provides two critical exceptions: (1) If a PERM labor certification or I-140 was filed at least 365 days before your 6-year limit, you can get 1-year extensions. (2) If you have an approved I-140 but cannot file I-485 due to visa number unavailability (common for India), you can get 3-year extensions. These extensions can continue indefinitely until a green card number becomes available.
