H-1B Work Visa

H-1B工作签证

Updated: March 2026

Overview

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).

Visa Categories and Cap Allocation

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.

Electronic Registration and Lottery Process

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.

H-1B Transfer and Extension

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.

H-4 Dependent Visa and EAD

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.

Alternative Options if Not Selected

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.

Eligibility Requirements

  • The applicant must hold a U.S. bachelor's degree or its foreign equivalent (or 12 years of progressive work experience as an equivalent)

Frequently Asked Questions

What should I do if I am not selected in the H-1B lottery?

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.

Can I change employers on H-1B?

Yes, through an H-1B Transfer. The new employer files a new I-129 petition — no new lottery registration is required. Under the portability rule, you may begin working for the new employer as soon as the transfer petition is received by USCIS.

What is the maximum duration of H-1B status?

The initial period of stay is 3 years, extendable for an additional 3 years, for a maximum of 6 years. If a PERM application has been filed or an I-140 approved, extensions beyond the 6-year limit are permitted under Section 106 of the AC21 Act.

Can an H-1B spouse work in the United States?

H-4 dependents are generally not authorized to work. However, if the H-1B holder's I-140 has been approved, the H-4 spouse may apply for an H-4 Employment Authorization Document (EAD).

What is the maximum H-1B duration?

The H-1B is initially granted for 3 years and can be extended once for an additional 3 years, for a total maximum of 6 years. However, if a PERM application has been filed before the end of the 5th year, or if an I-140 has been approved, extensions beyond the 6-year limit are available under Sections 106 and 104(c) of the AC21 Act, in 1-year or 3-year increments respectively, until the green card process is complete. In practice, many H-1B holders maintain status well beyond 6 years.

What employers are cap-exempt?

Employers exempt from the annual H-1B cap include: institutions of higher education (e.g., universities), nonprofit organizations affiliated with institutions of higher education, nonprofit research organizations, and governmental research organizations. H-1B petitions filed by these employers may be submitted at any time of year without entering the lottery. However, if the worker later transfers to a cap-subject private employer, they must be selected through the lottery.

What are H-1B filing fees?

H-1B filing fees include multiple components: the I-129 base filing fee of $460, the ACWIA training fee of $750 (employers with fewer than 25 employees) or $1,500 (25 or more employees), the fraud prevention fee of $500, and the public law education fee of $150 (applicable to employers with 50+ employees). Premium Processing (Form I-907) costs an additional $2,805. The annual electronic registration fee is $215 per beneficiary. Attorney fees vary but typically range from $2,000 to $5,000. All government filing fees must be paid by the employer.

Can I apply for H-1B while on OPT?

Yes. While on OPT (including STEM OPT extension), your employer can submit an H-1B electronic registration for the annual lottery. If selected and approved, the H-1B takes effect on October 1. During the OPT-to-H-1B transition, if your OPT expires before October 1, you may qualify for a "Cap-Gap" extension that allows you to continue working and maintaining lawful status until the H-1B becomes effective. Cap-Gap protection applies to F-1 students who have a pending or approved H-1B petition.

What are common reasons for H-1B denial?

Common denial reasons include: (1) the position does not qualify as a "specialty occupation" — USCIS determines the job does not require a bachelor's degree in a specific field; (2) degree-occupation mismatch — the applicant's degree field is not directly related to the job duties; (3) unclear employer-employee relationship — particularly in third-party worksite (client site) placements; (4) wage below the prevailing wage as determined by DOL; and (5) insufficient or inconsistent documentation. A thorough review with an attorney before filing is strongly recommended.

Can I travel during H-1B processing?

Caution is advised. If an H-1B petition is pending, departing the U.S. may cause the application to be deemed abandoned (unless you hold valid Advance Parole or a valid visa). If you are changing status from another classification (e.g., F-1/OPT) to H-1B, departing after your I-94 expires may prevent you from returning in your prior status. It is generally recommended to wait until the H-1B is approved and you have a valid visa stamp before traveling internationally. For H-1B Transfer cases, traveling with a valid existing H-1B visa stamp is generally safe.

What is Premium Processing?

Premium Processing is an expedited adjudication service offered by USCIS. By filing Form I-907 and paying a $2,805 fee, USCIS guarantees a decision (approval, denial, RFE, or NOID) within 15 business days. If USCIS fails to respond within the 15-day window, the Premium Processing fee is refunded. Premium Processing is available for new H-1B petitions, transfers, and extensions. Note: if an RFE is issued, the 15-day clock restarts after the RFE response is submitted.

Can I change status to H-1B within the US?

Yes. If you are in the U.S. in a valid nonimmigrant status (such as F-1, L-1, O-1, etc.) that has not expired, you may request a "Change of Status" as part of the H-1B approval, avoiding the need to depart and attend a consular interview. The H-1B status change takes effect on October 1 for cap-subject cases. Important: you must not leave the U.S. while the change of status request is pending, as departure will be treated as abandonment of the request. If your current status has expired or you have accrued unlawful presence, you must depart and obtain a visa stamp at a consulate.

How long does H-1B processing take?

The overall H-1B timeline depends on the processing method. Regular processing currently takes approximately 3-6 months for USCIS adjudication. Premium Processing guarantees a decision within 15 business days for an additional $2,805 fee. Preparation time (LCA filing takes about 7 days, document compilation takes 2-4 weeks) and subsequent visa stamping (if abroad) require additional time. From start of preparation to commencement of employment, regular processing takes approximately 4-8 months total, while Premium Processing can reduce this to 2-3 months.

Can I work for two employers simultaneously on H-1B?

Yes. H-1B permits concurrent employment, meaning you may work for two or more employers simultaneously. Each employer must file a separate I-129 petition and obtain individual approval, with an independent LCA for each position. The second H-1B petition does not require lottery selection (since the beneficiary already holds H-1B status). Each employer must independently meet all H-1B requirements, including paying the prevailing wage for their respective position. This arrangement is very common in academia and the consulting industry.

How do F-1 students transition to H-1B?

The typical F-1 to H-1B pathway is: (1) after graduation, apply for OPT for 12 months of work authorization (STEM majors may extend an additional 24 months); (2) during OPT, secure an employer willing to sponsor an H-1B; (3) each March, the employer submits an H-1B electronic registration for the lottery; (4) if selected, file the full I-129 petition; (5) H-1B takes effect October 1. If OPT expires before October 1, the Cap-Gap policy automatically extends F-1 status and work authorization until the H-1B becomes effective. Students not selected may continue on STEM OPT and re-enter the lottery the following year.

What is the grace period after H-1B termination?

Under regulations effective since 2017, H-1B holders receive a 60-day grace period after employment termination. During these 60 days, you may: (1) find a new employer and file an H-1B Transfer petition; (2) change to another nonimmigrant status (such as B-1/B-2 visitor visa); or (3) arrange departure from the U.S. The 60-day grace period may be used only once during the entire H-1B validity period. Note that if the H-1B I-94 expiration date falls before the 60 days, the grace period ends on the I-94 expiration date. Consulting an attorney immediately after termination is strongly recommended.

What is the H-1B visa stamping process?

After H-1B approval, if you need a visa stamp in your passport, you must attend an interview at a U.S. consulate abroad. The process is: (1) complete Form DS-160 online and pay the $185 visa fee; (2) schedule an interview appointment; (3) attend the interview with your I-797 approval notice, valid passport, DS-160 confirmation, employer support letter, and educational credentials; (4) after approval, the passport with the visa stamp is typically returned within 3-7 business days. Chinese applicants usually interview at U.S. embassies/consulates in Beijing, Shanghai, Guangzhou, or Shenyang. First-time H-1B visa applicants face a 10%-20% chance of Administrative Processing, which may take 1-8 weeks.

What is the LCA for H-1B?

The LCA (Labor Condition Application) is a prerequisite for every H-1B petition, filed by the employer with the Department of Labor (DOL) on Form ETA 9035. Through the LCA, the employer attests that: (1) the H-1B worker will be paid no less than the prevailing wage or the actual wage paid to similarly employed workers, whichever is higher; (2) the H-1B employment will not adversely affect working conditions of U.S. workers in the same occupation; (3) there is no strike or lockout at the worksite. The LCA is typically approved within 7 business days. The employer must also post the LCA notice at the worksite or provide electronic notification. A separate LCA is required for each H-1B work location.

Can H-1B workers work remotely?

Yes, but LCA compliance is required. The H-1B LCA is filed for a specific work location (Metropolitan Statistical Area). If the remote work location is within the same MSA, no modification is generally needed. However, if the remote location is in a different MSA (e.g., moving from New York to California), the employer must file a new LCA and an H-1B Amendment. Short-term business travel (generally not exceeding 30-60 days per year at another location) typically qualifies for the "Short-term Placement" exception. Since the 2020 pandemic, USCIS has increased scrutiny of remote work H-1B compliance, so confirming the specific arrangement with an attorney is recommended.

How is "specialty occupation" defined for H-1B?

Under INA Section 214(i) and 8 C.F.R. Section 214.2(h)(4)(ii), a specialty occupation must meet at least one of the following: (1) the position normally requires at least a bachelor's degree or equivalent as a minimum (industry standard); (2) the degree requirement is common in the industry, or the position is so complex or unique that only degreed individuals can perform it; (3) the employer normally requires a degree for the position; (4) the nature of the duties is so specialized that the knowledge required is usually associated with a bachelor's degree. USCIS has tightened scrutiny of specialty occupation claims in recent years, particularly for computer-related positions and entry-level roles.

How is the H-1B prevailing wage determined?

The prevailing wage is determined by the DOL based on the position's SOC Code (Standard Occupational Classification), work location, and wage level (Level 1-4). Employers can look up wages through the DOL's Foreign Labor Certification Data Center online or submit a formal PWD request for an official determination. The four levels represent: Level 1 (entry-level, approximately 17th percentile), Level 2 (qualified, approximately 34th percentile), Level 3 (experienced, approximately 50th percentile), and Level 4 (fully competent, approximately 67th percentile). The H-1B employer must pay the higher of the prevailing wage or the actual wage. An excessively low wage level may trigger an RFE or denial.

What is an H-1B site visit?

USCIS's Fraud Detection and National Security (FDNS) unit conducts unannounced worksite inspections (site visits) of H-1B employers and beneficiaries. Inspectors verify: (1) whether the beneficiary is physically working at the location specified in the I-129 petition; (2) whether the beneficiary's actual duties match the petition description; (3) whether the company is genuinely operating. Visits may occur during H-1B adjudication or after approval. Both the beneficiary and employer should answer questions truthfully. Inconsistencies discovered during the visit may result in an RFE, NOID, or revocation of an approved H-1B. Employers are advised to inform H-1B employees about the possibility of site visits and ensure they understand their job descriptions and work arrangements.
