The H-1B is the most widely used U.S. work visa, allowing American employers to hire foreign professionals in "specialty occupations." An H-1B visa is initially valid for 3 years and can be extended up to a maximum of 6 years. Each fiscal year, 65,000 regular-cap visas and 20,000 advanced-degree (Master's Cap) visas are allocated through an electronic registration lottery system. If the beneficiary has initiated the green card process during H-1B status (i.e., a PERM application is filed or the I-140 is approved), extensions beyond the 6-year limit are available under the American Competitiveness in the Twenty-First Century Act (AC21).
The H-1B visa is one of the primary work visa categories in the United States, allowing U.S. employers to hire foreign workers in "specialty occupations" that require at least a bachelor's degree or its equivalent. Each fiscal year, Congress allocates a total of 85,000 cap-subject H-1B visas: 65,000 under the regular cap and an additional 20,000 reserved for beneficiaries who hold a U.S. master's degree or higher (the "advanced degree exemption").
Importantly, not all H-1B petitions are subject to the annual cap. Cap-exempt employers — including institutions of higher education, nonprofit entities affiliated with universities, nonprofit research organizations, and governmental research organizations — may file H-1B petitions at any time throughout the year without regard to the numerical limitations. Workers employed by cap-exempt organizations do not count against the annual quota, eliminating the uncertainty of the lottery process. Understanding whether a prospective employer qualifies as cap-subject or cap-exempt is a critical first step in any H-1B visa strategy.
Additionally, citizens of Chile and Singapore are allocated 1,400 and 5,400 H-1B1 visas respectively under free trade agreements. Any unused H-1B1 numbers roll over into the following fiscal year's regular H-1B cap.
Since 2020, USCIS has implemented an electronic registration system for the H-1B cap selection process, significantly streamlining the lottery. Each March, employers (or their authorized attorneys) must submit electronic registrations through the USCIS online portal during a designated registration window, paying a $215 fee per registration. The registration period typically lasts two to three weeks. Only basic employer and beneficiary information is required at this stage — no supporting documentation or complete petition materials need to be filed.
USCIS employs a "beneficiary-centric selection" rule, meaning that regardless of how many employers register the same beneficiary, that individual is counted only once in the selection pool. This policy effectively prevents the practice of submitting multiple registrations to improve odds. Selection results are typically announced in late March to early April, with selected registrations updated to "Selected" status. Due to a surge in registrations in recent years (over 780,000 in FY2024), selection rates have dropped to approximately 25-30%.
Once selected, employers have a 90-day filing window to submit the complete H-1B petition (Form I-129 with all supporting documents) to USCIS. The H-1B employment start date is typically October 1 (the beginning of the new fiscal year). Failure to file within the designated window forfeits the selection. For those not selected, it is advisable to promptly evaluate alternative immigration options and begin preparing for the next year's lottery cycle.
The H-1B transfer mechanism provides critical flexibility for foreign workers already holding valid H-1B status. When changing employers, the new employer does not need to go through the H-1B lottery again — they simply file a new H-1B petition (Form I-129) with USCIS. Crucially, under the "portability rule," the beneficiary may begin employment with the new employer as soon as USCIS receives the transfer petition, without waiting for final adjudication. This provision greatly facilitates career mobility for H-1B workers.
Regarding the validity period, the standard H-1B visa is granted for a maximum of six years. However, the American Competitiveness in the Twenty-First Century Act (AC21) provides important extension exceptions: if the employer has filed a PERM labor certification (at least 365 days before the end of the six-year period), or if an I-140 immigrant petition has been approved, the H-1B holder may extend status beyond six years in one-year or three-year increments. This mechanism ensures that H-1B workers waiting in green card backlogs are not forced to leave the United States due to visa expiration.
Additionally, when there is a material change in the H-1B worker's job location, title, or duties, the employer may need to file an H-1B amendment with USCIS. For example, relocating from a New York office to a California branch, or being promoted from Software Engineer to Director of Technology, typically requires a timely amendment filing to maintain valid immigration status.
The H-4 visa is a dependent visa category designated for the spouses and unmarried children under 21 of H-1B visa holders. H-4 visa holders may reside lawfully in the United States, and children may attend public or private schools. The H-4 status validity is tied to the principal applicant's H-1B status — when the H-1B is extended, the H-4 must be extended accordingly.
Since 2015, USCIS has permitted eligible H-4 spouses to apply for Employment Authorization Documents (EAD). The primary eligibility requirement is that the H-1B principal's I-140 immigrant petition has been approved, or the H-1B principal has been granted an extension beyond the standard six-year period under the AC21 Act. With an H-4 EAD, the spouse may work for any U.S. employer without restriction on employer or position, and may also engage in self-employment.
H-4 EAD processing times currently range from approximately 3 to 6 months, with longer wait times in recent years due to increased filing volumes. It is important to note that minor children holding H-4 status, while permitted to study in the United States, may not apply for work authorization or engage in any paid employment. Furthermore, H-4 children "age out" and lose their H-4 status upon turning 21, at which point they must transition to another lawful status (such as F-1 student status). For dual-income families, the H-4 EAD is a vital tool for maintaining financial stability and serves as essential support during what is often a multi-year green card waiting period.
Not being selected in the H-1B lottery does not mean the end of the road for working in the United States. Applicants should promptly evaluate multiple alternative pathways to maintain lawful status and career continuity. One of the most common alternatives is the O-1 visa for individuals with extraordinary ability — the O-1 has no annual cap, requires no lottery, and can be filed year-round. For individuals with distinguished achievements in science, arts, education, business, or athletics, the O-1 offers an efficient work visa pathway.
For applicants employed by multinational companies, the L-1 intracompany transferee visa is an excellent option — L-1 visas are also exempt from the H-1B cap. If the applicant is currently on STEM OPT, they may apply for the STEM OPT extension, gaining an additional 24 months of work authorization on top of the initial 12-month OPT period, for a total of 36 months. This provides ample time to re-enter the H-1B lottery in subsequent years.
For well-qualified applicants, directly filing for an EB-1A Extraordinary Ability green card or a National Interest Waiver (NIW) green card is also a viable strategy. Both categories allow self-petitioning without employer sponsorship, and EB-1A is currently available (no backlog) for most countries. Additional alternatives include the E-2 Treaty Investor visa (for those with investment capacity), the TN visa (available only to Canadian and Mexican citizens), and seeking employment with cap-exempt employers such as universities. Finally, applicants who are not selected should prepare to re-register for the H-1B lottery in the following fiscal year.
The applicant must hold a U.S. bachelor's degree or its foreign equivalent (or 12 years of progressive work experience as an equivalent)
The position must qualify as a "specialty occupation" — one that typically requires at least a bachelor's degree in a specific field
A U.S. employer must sponsor the petition and pay at least the prevailing wage as determined by the Department of Labor
The employer must file a Labor Condition Application (LCA) with the Department of Labor (DOL)
Common qualifying occupations include engineers, software developers, data scientists, accountants, architects, and physicians
Electronic Registration
Each March, the employer submits an electronic registration in the USCIS system for the beneficiary, paying a $215 registration fee. USCIS conducts a random lottery selection.
Lottery Results
Results are typically announced in late March to early April. Selected registrants have a 90-day window to file the full petition.
LCA Filing
The employer files a Labor Condition Application (ETA 9035) with the Department of Labor, attesting to payment of the prevailing wage and compliance with working conditions. LCA approval usually takes 7 days.
I-129 Petition
The employer files Form I-129 with USCIS along with the complete petition package, including a support letter, credential evaluations, and an employment agreement.
Adjudication / RFE
USCIS reviews the petition and may issue a Request for Evidence (RFE). Regular processing takes approximately 3-6 months; Premium Processing guarantees a response within 15 business days.
Visa Stamping / Entry
Once approved, applicants outside the U.S. must attend a consular interview. Those in the U.S. in valid status may change status without departing.

H-1B vs L-1 vs O-1 Comparison
| Feature | H-1B | L-1 | O-1 |
|---|---|---|---|
| Type | Work visa | Intracompany transfer | Extraordinary ability |
| Employer required | Yes | Yes (related entity) | Yes (agent OK) |
| Cap / Lottery | Yes (85,000/year) | No | No |
| Duration | 3+3 years, max 6 years | L-1A up to 7 yrs, L-1B up to 5 yrs | 3 years (renewable indefinitely) |
| Spouse work auth | H-4 EAD (if I-140 approved) | L-2 EAD | O-3 (no EAD) |
| Green card path | EB-2/EB-3 (PERM required) | EB-1C | EB-1A / EB-1B |
| Min. education | Bachelor's in related field | 1 year with qualifying company | Extraordinary ability (no fixed degree) |
Consider alternatives such as the O-1 visa (for individuals with extraordinary ability — no annual cap), the L-1 visa (if you have a qualifying foreign affiliate), a cap-exempt employer (universities or nonprofit research organizations), continuing on OPT/STEM OPT and re-entering the lottery the following year, or filing directly for an EB-1A or NIW green card.
