The United States attracts workers and employers from around the world, offering a wide range of temporary visa categories for those seeking to carry out specific employment in the country. These visas are governed by U.S. immigration law and designed to balance workforce needs with compliance safeguards. For employers, selecting the correct route and preparing the right documentation is critical to securing lawful status for overseas hires. For applicants, understanding eligibility rules and procedures helps avoid delays and refusals.
What this article is about: This guide gives employers and applicants a structured overview of the main U.S. employment visa categories. It explains how petition-based categories work, highlights the application steps, outlines fees and documents typically required, and sets out the treatment of spouses and children. It also signposts to authoritative resources for further detail on each route, including H, L, O, P, Q, J, I, E and TN/TD visas.
Section A: Temporary Employment Visas (H, L, O, P, Q)
This section explains the principal petition-based temporary worker categories used by U.S. employers to bring nonimmigrant workers to the United States. It reflects current USCIS and Department of State guidance on process, documents, fees and family members.
These routes are employer-led and typically require approval of Form I-129 before the visa application. Each is restricted to the role, employer and terms described in the petition and must be monitored for ongoing compliance.
1. Overview
H visas — specialty occupation (H-1B), seasonal agricultural (H-2A), seasonal/non-agricultural (H-2B) and trainee/special education exchange (H-3). H-1B roles require a certified Labor Condition Application. H-3 is for structured training; any productive work must be incidental to the training plan.
L visas — intra-company transferees (L-1A managers/executives, L-1B specialized knowledge) moving to a qualifying U.S. entity under common ownership/control.
O visas — individuals with extraordinary ability/achievement (O-1). Support personnel (O-2) may accompany only artists, athletes, and MPTV productions; they must be integral to the performance and have a qualifying prior working relationship.
P visas — athletes and entertainers: P-1A (athletes/teams), P-1B (entertainment groups), P-2 (reciprocal exchange), P-3 (culturally unique programs). Related “S” classifications cover qualifying support staff.
Q visas — international cultural exchange run by a qualified U.S. employer that maintains an established cultural exchange program; the employer files the petition.
2. How to apply
Step 1: U.S. employer (or agent, where permitted) files Form I-129 with evidence. Category-specific prerequisites apply (for example, certified LCA for H-1B; consultations for many O/P cases; program evidence for Q).
Step 2: On approval, USCIS issues Form I-797. The worker completes DS-160, pays the MRV fee, books the visa interview, and prepares category-specific proofs. Canadians seeking L or some other classifications may process at a port of entry only where permitted by law; most categories proceed by visa stamping after petition approval.
3. Fees
Expect a combination of: base I-129 filing fee (increased under the April 2024 fee rule), category-specific surcharges (for H and L petitions this may include ACWIA, Fraud Prevention and Detection, Pub. L. 114-113, and the Asylum Program Fee), optional Premium Processing, plus the consular MRV fee. Always check the current USCIS Fee Schedule and form instructions before filing.
4. Required documentation
- Valid passport and DS-160 confirmation
- USCIS approval notice (Form I-797) and full copy of the I-129 packet
- Employer support letter describing role, wages, location and terms
- Any prerequisite certifications/consultations (for example, certified LCA for H-1B)
- Evidence of eligibility (degrees, experience evaluations, awards, press, itineraries)
5. Spouses and children
Dependants usually use matching categories: H-4, L-2, O-3, P-4, Q-3. L-2 spouses are employment-authorized incident to status; an EAD card is optional for I-9 purposes. Children may study but cannot work.
Section summary
H, L, O, P and Q are petition-based and employer-driven. File I-129 with category-specific evidence, track fee components, and present a complete package at the visa stage. Treat training (H-3), support roles (O-2) and cultural exchange (Q) according to their specific limits. Keep family work rights clear, particularly for L-2 spouses who have work authorization incident to status.
This section explains the Exchange Visitor (J) visa, a category overseen by the U.S. Department of State. It is not petition-based but requires sponsorship by a designated program, SEVIS compliance, and in some cases a two-year foreign residence requirement under INA 212(e).
Section B: Exchange Visitor Visa (J)
The J program facilitates cultural, educational and professional exchange. It covers a wide range of categories, from research scholars, professors and teachers, to au pairs, camp counsellors, interns and participants in summer work travel.
1. Overview
The J visa allows participation in programs that promote mutual understanding between the U.S. and other nations. Designated sponsors, not USCIS, control entry into the category. They issue the Form DS-2019 and ensure program compliance. Some participants are subject to the two-year home residency requirement, meaning they must return home for two years before applying for certain other U.S. visas or permanent residence, unless they obtain a waiver.
2. How to apply
Step 1: Applicant secures acceptance into a Department of State-designated program. The sponsor issues Form DS-2019.
Step 2: Pay the SEVIS I-901 fee, complete Form DS-160, and schedule the consular interview. At the interview, applicants must show eligibility, intent to participate as authorised, and sufficient home ties.
3. Fees
- SEVIS I-901 fee
- Consular MRV visa fee
- Additional sponsor/program fees (set individually)
4. Required documentation
- Form DS-2019 issued by the sponsor
- SEVIS I-901 payment confirmation
- DS-160 confirmation page and valid passport
- Proof of financial support
- Acceptance letter or contract from the program sponsor
5. Spouses and children
Dependants may apply for J-2 visas. Each dependant requires their own DS-2019. J-2 spouses may apply for work authorisation after arrival in the U.S. by filing Form I-765. Children may attend school but cannot work. All dependants must maintain status tied to the principal J visa holder’s program.
Section summary
The J visa provides access to U.S. exchange programs under sponsor oversight. It requires DS-2019, SEVIS registration and careful compliance with program rules. Some categories impose a two-year home residency requirement, affecting future immigration options. J-2 dependants can join, with spouses eligible for work authorisation. Sponsors hold key compliance responsibility.
This section explains the Media (I) visa for representatives of foreign media organisations. It is a non-petition category governed by Department of State rules and limited strictly to bona fide news-gathering activities.
Section C: Media Visa (I)
The I visa supports foreign journalists, film crews and broadcasters travelling to the U.S. to report, document or cover events for an overseas audience. It is not intended for entertainment, commercial advertising or scripted productions.
1. Overview
Eligible activities include reporting on current events, producing news programming and covering cultural or sporting events of journalistic value. The visa does not authorise work on entertainment projects, reality television or marketing campaigns. Applicants must demonstrate they are employed by or under contract with a recognised foreign media organisation.
2. How to apply
Applicants complete the DS-160 form, pay the MRV fee and schedule an interview at a U.S. consulate. A supporting letter from the employer or media outlet confirming the applicant’s professional role, assignment and duration of stay is usually required. No USCIS petition is needed in advance.
3. Fees
- Consular MRV visa application fee
- Any incidental costs, such as obtaining employer confirmation letters or accreditation
4. Required documentation
- Valid passport and DS-160 confirmation page
- Letter from employer or media organisation detailing the assignment
- Evidence of press or journalist credentials
- Samples of published or broadcast work, if requested
5. Spouses and children
Dependants may be issued accompanying I visas. They can live in the U.S. for the duration of the journalist’s assignment and attend school, but they are not eligible for work authorisation. Their stay is tied to the principal applicant’s status and assignment period.
Section summary
The I visa is a streamlined option for legitimate representatives of foreign media. It does not require a USCIS petition but depends on strong employer support and proof of professional credentials. Dependants may accompany but cannot work. The visa’s scope is narrow: strictly news-related, not entertainment or commercial productions.
This section explains the principal treaty-based employment categories and the North American professional route. These visas are not petition-based at the consular stage but still impose strict eligibility requirements and compliance checks.
Section D: Treaty-Based and Professional Visas (E and TN/TD)
The E and TN/TD visas allow nationals of certain countries to work in the United States where a treaty or trade agreement applies. They are distinct from petition-based routes such as H or L, but applicants must still meet evidential thresholds and maintain nonimmigrant intent.
1. Treaty Trader & Investor Visa (E)
The E visa is available to nationals of countries that have treaties of commerce and navigation with the United States. It covers:
- E-1 treaty traders — engaging in substantial trade between the U.S. and the treaty country
- E-2 treaty investors — making and directing a substantial investment in a U.S. business
- E employees — executives, managers or specialists from treaty enterprises
Applicants must prove treaty nationality, ownership or investment in a qualifying enterprise and intent to depart when their status ends. No USCIS petition is needed for an initial consular application. However, extensions or change of status inside the U.S. require filing Form I-129 with USCIS.
2. USMCA Professional Worker Visa (TN/TD)
The TN visa permits Canadian and Mexican professionals to work in the U.S. under the United States–Mexico–Canada Agreement (USMCA, formerly NAFTA). It applies only to specified occupations listed in the treaty, such as engineers, scientists, accountants, and teachers. Applicants must present evidence of nationality, a qualifying job offer from a U.S. employer, and proof of professional qualifications.
Application process: Canadians may apply directly at a U.S. port of entry with required documentation. Mexican nationals must obtain a TN visa at a consulate before entry. USCIS petition approval is not required unless seeking change of status or extension from inside the U.S.
Dependants: Spouses and children may accompany under TD status. They can study but are not permitted to work.
Section summary
E and TN/TD visas facilitate cross-border commerce and professional services without the petition step required by H or L categories. E visas depend on treaty nationality and substantial trade or investment. TN visas support specified professions under USMCA. Both require strict evidential documentation and confirmation of intent to depart, while dependant rights are limited to residence and study, not employment.
Frequently Asked Questions
1. What is the difference between H-1B and L-1 visas?
The H-1B visa is for specialty occupations requiring a degree or equivalent, and it requires a certified Labor Condition Application from the Department of Labor. The L-1 visa is for intra-company transferees moving to a U.S. branch, subsidiary or affiliate in managerial, executive or specialised knowledge roles. H-1B is subject to annual caps, while L-1 is not.
2. Can dependants of work visa holders study or work in the U.S.?
Children of most employment visa holders can attend school in the U.S. but cannot work. Some spouses, such as L-2 and J-2, may work. L-2 spouses are authorised for employment incident to status, while J-2 spouses may apply for work authorisation by filing Form I-765. H-4 spouses generally cannot work unless the principal H-1B is on a qualifying path to permanent residence.
3. Do all U.S. work visas require employer sponsorship?
No. Petition-based visas (H, L, O, P, Q) require employer sponsorship and USCIS petition approval. Other categories, such as I (media), E (treaty trader/investor) and TN (for Canadians and Mexicans), do not need a petition at the consular stage but still require employer/job documentation and proof of eligibility.
4. How long do employment visas take to process?
Processing times vary. Petition-based categories may take weeks or months depending on USCIS backlogs and consular appointment availability. Premium Processing can expedite USCIS petitions. Non-petition visas, such as TN for Canadians or I visas, can sometimes be processed in days at the border or consulate.
5. Can employment visas lead to a green card?
Some work visas can provide a route to permanent residence. H-1B workers may be sponsored for an employment-based green card. L-1A executives and managers may transition to EB-1C permanent residence. However, many temporary visas, such as J and Q, do not generally lead to a green card, and J participants may face a two-year home residency requirement before applying for immigrant status unless waived.
Conclusion
The United States provides a wide spectrum of employment visa options, each with distinct eligibility criteria, procedures and compliance rules. Petition-based visas such as H, L, O, P and Q require employer sponsorship and USCIS approval before consular processing. Non-petition categories like I, E and TN/TD rely on documentation of professional role, treaty nationality or trade/investment status rather than a petition.
Employers and applicants should carefully identify the most appropriate route at the outset. Fee structures, processing timelines, supporting evidence and rights of dependants differ across categories. In particular, employers must ensure petitions and labour certifications are filed correctly, while applicants must be able to prove qualifications, purpose of travel and nonimmigrant intent where required.
For some categories, such as H-1B and L-1A, there may be longer-term immigration options, while others are strictly temporary. Compliance obligations continue after approval and can affect both the employer and the worker.
Key takeaway: Matching the correct visa route to the employment scenario and presenting a well-prepared, legally compliant application will reduce delays and refusals. Accurate sponsorship and thorough documentation are central to maintaining lawful status.
