US Work Visa Types: Every Option to Work Legally in America

US work visa types are nonimmigrant and immigrant classifications that let foreign nationals work legally in the United States for a sponsoring employer, a treaty business or on the strength of their own extraordinary ability. The main temporary options are the H-1B, L-1, O-1, TN, E and H-2 visas. Permanent rights are different. They come from the EB-1 to EB-5 employment-based green cards.

Key Takeaways

• The H-1B is the main US visa for specialty occupations. It offers 65,000 regular slots plus 20,000 slots for US master’s graduates each fiscal year.
• Citizens of Canada and Mexico (TN), Australia (E-3), and Chile and Singapore (H-1B1) have dedicated professional visas outside the H-1B lottery.
• Foreign nationals without a job offer can pursue the E-2 treaty investor visa, the EB-1A green card, the EB-2 National Interest Waiver or the EB-5 investor green card.
• A work visa is a travel document used for entry. An Employment Authorization Document (EAD) is a separate work permit card issued by USCIS.
• The H-1B and L-1 visas allow dual intent, so holders can apply for a green card without violating their temporary status.

What Are the Main Types of US Work Visas?

The main types of US work visas are the H-1B, H-1B1, H-2A, H-2B, L-1, O-1, P, Q, R, TN, E-1, E-2 and E-3 temporary visas, plus the EB-1 to EB-5 employment-based green cards. Temporary visas tie work rights to a job or business. Green cards don’t. They grant permanent residence and the right to work for any employer. For more on this, read our guide on how to renew a work visa.

Every American work visa falls into one of two legal groups. Nonimmigrant visas grant temporary stays tied to a specific purpose, employer or business, while immigrant visas, commonly called green cards, grant permanent residence. Each group follows its own rules.

Three federal agencies share the work. US Citizenship and Immigration Services (USCIS) approves employer petitions, and the US Department of State issues visas at embassies and consulates abroad. The US Department of Labor (DOL) certifies wages and runs labor market tests.

Temporary Nonimmigrant Work Visas

Temporary work visas let a foreign national work for a defined period, usually for one sponsoring employer. The paperwork starts on the employer’s side. Most categories require Form I-129, Petition for a Nonimmigrant Worker, filed with USCIS before the worker applies for a visa stamp.

This table lines up the main temporary work visas against their annual caps and stay limits.

Visa	Best For	Annual Cap (Visas)	Maximum Stay (Years)
H-1B	Degree-holding specialty professionals	65,000 plus 20,000 advanced degree	6, extendable with green card filing
H-1B1	Chilean and Singaporean professionals	1,400 Chile, 5,400 Singapore	1 per renewable period
E-3	Australian specialty professionals	10,500	2 per renewable period
TN	Canadian and Mexican USMCA professionals	No cap	3 per renewable period
L-1A	Multinational managers and executives	No cap	7
L-1B	Specialized knowledge employees	No cap	5
O-1	Individuals with extraordinary ability	No cap	3, then 1-year extensions
E-2	Treaty country investors	No cap	Up to 2 per renewable admission
H-2A	Seasonal agricultural workers	No cap	3
H-2B	Seasonal nonagricultural workers	66,000	3

Uncapped visas skip the lottery. That makes the TN, L-1 and O-1 faster routes for any worker who qualifies, because no random selection stands between the petition and the job.

Permanent Employment-Based Green Cards

Employment-based green cards give permanent residence and the right to work for any US employer. Supply is set by statute. The Immigration and Nationality Act sets a baseline of 140,000 employment-based green cards per fiscal year, split across five preference categories.

This table compares the five employment-based green card categories and whether each needs a job offer.

Category	Who Qualifies	Job Offer Needed
EB-1A	Extraordinary ability in any field	No
EB-1B	Outstanding professors and researchers	Yes
EB-1C	Multinational managers and executives	Yes
EB-2	Advanced degree or exceptional ability	Yes, unless NIW approved
EB-3	Skilled workers, professionals, other workers	Yes
EB-4	Special immigrants, including religious workers	Varies by subgroup
EB-5	Investors creating 10 US jobs	No

Investment minimums differ by project. The EB-5 Reform and Integrity Act of 2022 sets the standard EB-5 investment at $1,050,000, and that amount drops to $800,000 for projects in a targeted employment areaor for infrastructure projects. Both figures are fixed by law.

How Many US Work Visa Types Exist?

No verified single count of US work visa types exists, because the total depends on whether subcategories such as L-1A and L-1B or O-1A and O-1B are counted separately. USCIS groups temporary work classifications under the H, L, O, P, Q, R, TN and E categories. The State Department agrees. Its temporary worker visa page lists the same groups.

A count by main letter classification gives a short list. Add every subcategory, such as H-2A, H-2B, O-1A, O-1B, P-1, P-2 and P-3, and the list grows much longer. Any source quoting one exact total is picking a counting method. It isn’t stating a legal fact.

People searching for US visa work types or US working visa types want one practical answer. The same goes for anyone looking up the type of work visas in US law. They want to know which category matches their situation.

Which US Work Visa Types Fit Your Profile?

The right choice among US work visa types depends on four facts: your nationality, whether you hold a job offer, your education level and whether you can invest capital. A degree plus a job offer points to the H-1B. If you already work for a multinational, the L-1 is the natural fit. Investors look at the E-2 or EB-5.

This table matches common applicant profiles to the visa options that fit them.

Your Profile	Best Visa Options	Key Requirement
Degree plus US job offer	H-1B	Lottery selection unless employer is cap-exempt
Canadian or Mexican professional	TN	Job on the USMCA professions list
Australian graduate with job offer	E-3	Specialty occupation and approved LCA
Chilean or Singaporean graduate	H-1B1	Specialty occupation and approved LCA
Transferring within my company	L-1A or L-1B	1 year with foreign affiliate in last 3
Top achiever in my field	O-1 or EB-1A	Sustained national or international acclaim
Investor from a treaty country	E-2	Substantial investment in an active business
Investor from any country	EB-5	$800,000 or $1,050,000 investment
No degree, seasonal job offer	H-2A or H-2B	Employer temporary labor certification
Advanced degree, no job offer	EB-2 NIW	Work benefits the US national interest
F-1 student near graduation	OPT, then H-1B	EAD issued by USCIS

Nationality changes the answer more than most readers expect. Take two software engineers, one Canadian and one Indian, holding identical job offers from the same US company. Their options differ. The Canadian can use the TN without a lottery, while the Indian national generally needs the H-1B.

Professional and Specialty Occupation Visas

Professional work visas cover jobs that require at least a bachelor’s degree or its equivalent in a specific field, and the H-1B is the main US visa for these specialty occupation roles. Typical H-1B workers sponsored by US employers include engineers, software developers, accountants, physicians, architects and university researchers. Each role needs that degree.

H-1B Specialty Occupation Visa

The H-1B lets a US employer hire a foreign professional for a specialty occupation. That term has a legal meaning. It describes a role requiring highly specialized knowledge and at least a bachelor’s degree in a specific specialty.

Wages come first. Before filing the petition, the employer submits a Labor Condition Application (LCA) on Form ETA-9035 to the DOL. That filing commits the employer to pay the higher of two amounts: the actual wage paid to similar workers or the prevailing wage for the role and location.

The H American visa types share the H prefix but serve different workers. Professionals use the H-1B, and Chilean and Singaporean professionals use the H-1B1. Seasonal workers fall under the H-2A and H-2B. Trainees get the H-3.

Cap-Subject vs Cap-Exempt H-1B Employers

Most private employers are cap-subject, which means their new H-1B hires must win the annual lottery. Cap-exempt employers don’t. They skip the lottery and can file at any time of year.

Cap-exempt employers include:

• Institutions of higher education, such as US universities and colleges
• Nonprofit entities related to or affiliated with a higher education institution
• Nonprofit research organizations
• Government research organizations

That’s good news for job changers. Workers already counted against the cap generally don’t re-enter the lottery when they move to a new H-1B employer.

Nationality-Specific Work Visas Most Readers Miss

Citizens of Canada, Mexico, Australia, Chile, Singapore and dozens of treaty countries qualify for dedicated US work visas that skip the H-1B lottery. Speed is the main draw. For qualifying workers, these visas often move faster than the H-1B, and each one ties eligibility to a trade agreement or treaty between the United States and the worker’s home country.

This table sets the nationality-specific visas side by side.

Visa	Eligible Nationals	Dual Intent	Spouse Can Work
TN	Canada, Mexico	No	No
E-3	Australia	No	Yes
H-1B1	Chile, Singapore	No	No
E-1 and E-2	Treaty country nationals	No	Yes

TN Visa for Canada and Mexico

The TN visa lets Canadian and Mexican citizens work in the US in professions listed under the United States-Mexico-Canada Agreement (USMCA). Engineers, accountants, scientists, computer systems analysts and management consultants all appear on that list. Renewals are open-ended. Each TN period lasts up to 3 years, and no fixed lifetime limit applies.

Canadian citizens can request TN status directly at a US port of entry or preclearance location, bringing a job letter and proof of their degree. Mexicans can’t. They must first apply for a TN visa at a US embassy or consulate.

Intent matters here. The TN requires nonimmigrant intent, so workers planning a green card often switch to the H-1B first or time their filings with an immigration attorney.

E-3 Visa for Australians

The E-3 visa lets Australian citizens work in specialty occupations in the US, with 10,500 visas available each fiscal year. No USCIS petition is needed. The employer files an LCA with the DOL, and the Australian worker applies directly at a US consulate.

E-3 status runs in periods of up to 2 years, and renewals have no fixed limit. Spouses gain too. E-3 spouses can work in the US.

H-1B1 Visa for Chile and Singapore

The H-1B1 visa lets citizens of Chile and Singapore work in specialty occupations under free trade agreements with the United States. Chile gets 1,400 visas a year. Singapore gets 5,400, and both allocations come out of the H-1B cap without being subject to the lottery.

Renewals are short. H-1B1 status runs in 1-year periods and requires nonimmigrant intent.

E-1 and E-2 Treaty Visas

Two treaty visas cover business owners. The E-1 treaty trader visa serves nationals of treaty countries whose companies carry on substantial trade, with more than 50% of that trade between the US and the treaty country. Investors use the E-2 treaty investor visa instead, which serves treaty nationals who invest substantial capital in an operating US business that they own at least 50% of or control.

The E-2 has no fixed minimum investment. Instead, the amount must be substantial relative to the cost of the business.

India and mainland China have no E-2 treaty with the US. That gap matters. Nationals of those countries need another route or a second nationality from a treaty country.

Intracompany Transfer and Talent Visas

Intracompany transfer and talent visas serve two groups. Employees moving to a US office of their current multinational employer use the L-1, and individuals with top-level achievement in their field use the O-1. Neither visa has an annual cap, so qualified applicants avoid the H-1B lottery entirely. Our guide on H1B visa requirements covers the steps in detail.

L-1A and L-1B Intracompany Transferee Visas

The L-1 visa lets a multinational company transfer an employee who has worked for a related foreign entity for at least 1 continuous year within the past 3 years. Managers and executives use the L-1A for up to 7 years. Employees with specialized knowledge get the L-1B, which lasts up to 5 years.

New offices start small. An employer opening a new US office receives an initial L-1 approval of 1 year, while large multinationals can file a blanket L petition to speed up repeat transfers. For more on this, read our guide on types of work visas.

The L-1A leads directly into the EB-1C green card category for multinational managers and executives. No labor certification is required.

O-1 Extraordinary Ability Visa

The O-1 visa serves individuals with extraordinary ability or achievement. It splits in two. Sciences, education, business and athletics fall under the O-1A, while the arts, motion pictures and television fall under the O-1B.

O-1A applicants can qualify with a major internationally recognized award. Without one, they must meet at least 3 of 8 regulatory criteria. Published material about their work counts as one criterion, and a high salary or original contributions of major significance count as others. Initial approval lasts up to 3 years, with 1-year extensions after that.

P, Q and R Visas for Performers and Religious Workers

Several smaller categories cover specialized groups:

• P-1: internationally recognized athletes and entertainment groups
• P-2: artists and entertainers in reciprocal exchange programs
• P-3: artists and entertainers in culturally unique programs
• Q-1: participants in international cultural exchange programs
• R-1: ministers and religious workers, for up to 5 years in total

Seasonal and Temporary Worker Visas

The seasonal US work visas are the H-2A for temporary agricultural jobs and the H-2B for temporary nonagricultural jobs such as hospitality, groundskeeping and seafood processing. Both require the employer to obtain a temporary labor certification from the DOL, which shows that no qualified US workers are available for the role. The paperwork is strict. Our guide on work visa vs work permit covers the steps in detail.

Eligibility also depends on citizenship. Only nationals of countries on the eligible countries list published by the Department of Homeland Security can normally use these visas.

H-2A Agricultural Worker Visa

The H-2A visa lets US farm employers hire foreign workers for seasonal or temporary agricultural work, and it has no annual cap. Employer duties are heavy. Farms must offer free housing to workers who can’t reasonably return home each day, along with meals or kitchen facilities and travel costs under program rules.

Stays can grow. H-2A workers can extend their stay up to a total of 3 years.

H-2B Nonagricultural Worker Visa

The H-2B visa covers temporary nonagricultural jobs that are seasonal, peakload, intermittent or one-time. Resort staff and groundskeepers fill many of these roles. Fish processors are another typical group.

Congress caps the H-2B at 66,000 visas per fiscal year, split into 33,000 for each half of the year. Extra visas can appear. The government sometimes releases supplemental H-2B visas when demand exceeds the cap.

Is the H-1B Visa a Lottery?

Yes, the H-1B visa uses a random lottery whenever electronic registrations exceed the annual cap of 65,000 regular visas plus 20,000 for holders of US master’s or higher degrees. Employers register candidates each spring. USCIS then selects registrations at random, and only selected candidates can be included in a full cap-subject petition.

The selection runs in two rounds. First, USCIS draws from all registrations for the 65,000 regular cap. A second draw then pulls from the remaining registrants with US master’s or higher degrees for the 20,000 advanced degree exemption, giving US graduate degree holders better odds.

Timing is fixed. Employers of selected registrants file full petitions starting April 1, but approved cap-subject workers can’t start before October 1, the first day of the federal fiscal year.

A presidential proclamation signed in September 2025 added a $100,000 payment requirement for certain new H-1B petitions. Its scope can change. Employers should confirm current coverage and exemptions on uscis.gov before registering a candidate.

Losing the lottery isn’t the end. Workers who aren’t selected can still reach the US through a cap-exempt employer, and nationals of eligible countries can use a nationality-specific visa such as the TN or E-3.

How Long Does an H-1B Visa Last?

An H-1B visa lasts up to 3 years at first and extends to a maximum of 6 years in total. Green card applicants can go further. Workers with a pending or approved green card process can get extensions beyond 6 years under the American Competitiveness in the Twenty-First Century Act (AC21).

Days abroad aren’t lost. Time spent outside the US during H-1B status can be recaptured and added back to the 6-year limit.

A worker who reaches the 6-year maximum without a qualifying green card filing must stay outside the US for 1 year. Then the clock resets. A fresh 6-year H-1B period becomes available to that worker.

Can I Get a US Work Visa Without a Job Offer?

Yes, foreign nationals can get US work rights without a job offer through four main routes. Those routes are the E-2 treaty investor visa, the EB-1A extraordinary ability green card, the EB-2 National Interest Waiver (NIW) and the EB-5 investor green card. The O-1 is different. It still requires a US employer or agent, though one agent can represent several employers.

This table compares the four main routes that need no traditional employer sponsor.

Path	Who It Suits	Main Test
E-2	Treaty nationals with capital	Substantial investment in an active US business
EB-1A	Top performers in any field	Sustained national or international acclaim
EB-2 NIW	Advanced-degree professionals	Work in the US national interest
EB-5	Investors from any country	$800,000 or $1,050,000 creating 10 jobs

The NIW has a set legal standard. It applies the three-part test from Matter of Dhanasar, a 2016 USCIS Administrative Appeals Office precedent decision.

Students have one more option. Those in F-1 status can work after graduation through Optional Practical Training (OPT), which gives 12 months of work authorization. Graduates in science, technology, engineering and mathematics (STEM) can add a 24-month extension.

Is a Work Visa the Same as a Work Permit?

No, a work visa is not the same as a work permit. A visa is a travel document stamped in a passport that allows a person to request entry to the US. An Employment Authorization Document (EAD) is a separate USCIS card, applied for on Form I-765, that proves permission to work.

A visa stamp only lets a traveler request entry at a US port. It doesn’t define status. That job belongs to the Form I-94 record created at entry, which shows the person’s status and the date by which they must leave.

A US work permit visa isn’t one single document. Work permission in the USA comes either from a status that includes work rights, such as the H-1B, or from an EAD.

Who Qualifies for an EAD

EAD eligibility depends on the applicant’s immigration category, and the list is long. Common EAD holders include:

• F-1 students on OPT
• H-4 spouses of H-1B workers who meet green card progress rules
• Green card applicants with a pending Form I-485
• Asylum applicants whose cases have been pending long enough under USCIS rules
• Refugees and people granted asylum
• Temporary Protected Status (TPS) beneficiaries

Can My Spouse Work on My US Work Visa?

Yes for some visas and no for others. L-2 and E spouses can work automatically. H-4 spouses of H-1B workers need an H-4 EAD, which depends on how far the worker’s green card case has progressed. Dependents of TN, O-1 and H-1B1 workers can’t work in the US at all.

This table compares spouse work rights by principal visa.

Principal Visa	Spouse Status	Spouse Can Work
H-1B	H-4	Only with H-4 EAD
H-1B1	H-4	No
L-1	L-2	Yes, incident to status
E-1, E-2, E-3	E dependent	Yes, incident to status
TN	TD	No
O-1	O-3	No
H-2A or H-2B	H-4	No

The H-4 EAD opens in two situations. Either the H-1B partner holds an approved Form I-140 immigrant petition, or that partner has extended H-1B status beyond 6 years under AC21. Spouses apply on Form I-765.

L-2 and E spouses gained work authorization incident to status after a 2021 lawsuit settlement with USCIS. Proof is now simpler. Their I-94 records show that they’re authorized to work.

Can a US Work Visa Lead to a Green Card?

Yes, a US work visa can lead to a green card. The H-1B and L-1 make the move easiest because both allow dual intent, meaning holders may pursue permanent residence while keeping their temporary status. The O-1 also tolerates a pending green card petition.

The typical employer-sponsored path follows four steps:

1. File a labor certification through the Program Electronic Review Management (PERM) system with the DOL on Form ETA-9089, unless the category is exempt.
2. File Form I-140, Immigrant Petition for Alien Worker, with USCIS.
3. Wait for the priority date to become current in the Visa Bulletin.
4. File Form I-485 to adjust status inside the US, or complete consular processing abroad.

Not every visa works this way. The TN, E-3, H-1B1 and E visas require nonimmigrant intent, so holders face more scrutiny when they travel or renew status after starting a green card case.

How the Visa Bulletin Affects Wait Times

The Visa Bulletin is a monthly State Department publication that shows which priority dates can move forward in each green card category and country. Each case carries a priority date. It’s usually the date the PERM application or Form I-140 was filed.

Per-country limits restrict each country to 7% of the total family and employment green cards issued each year. Applicants born in high-demand countries such as India and China face much longer waits as a result. Exact delays vary. No verified figure for current wait times is available here, so check the latest Visa Bulletin before planning.

How to Get a US Work Visa

Getting a US work visa follows a set order. Choose the right category, secure a sponsor or qualifying investment, complete Department of Labor filings, obtain USCIS approval when required, then apply at a US embassy or consulate. Most applicants finish the consular steps in their home country.

1. Identify the visa category that matches your nationality, job offer, education and capital.
2. Secure a US employer, agent or qualifying investment that supports that category.
3. Confirm that the employer files the LCA or temporary labor certification with the DOL when the category requires one.
4. Wait for USCIS to approve Form I-129. Skip this step for E-1, E-2, E-3, H-1B1 and TN applications made at a consulate or the border.
5. Complete Form DS-160, the online nonimmigrant visa application, and pay the consular fee.
6. Attend the visa interview at a US embassy or consulate with your passport, approval notice and job documents.
7. Check your I-94 record online after entry to confirm your status and end date.

Already in the country? Workers in the US in valid status can often skip consular processing, because their employer files a change of status request on Form I-129 instead.

Conclusion

US work visa types will keep shifting as Congress and federal agencies adjust caps and fees, and presidential proclamations can change selection rules too. Preparation wins. The fastest workers match their profile to one category early and gather degree and employment evidence before an offer arrives. They also plan the green card path from the first petition.

Don’t rely on old guides. Confirm every form and fee on uscis.gov and travel.state.gov before filing, and review the Visa Bulletin each month if a green card is the goal. Complex cases call for an immigration attorney licensed in any US state.
