You've heard a few of these letters and numbers thrown around. A recruiter mentioned H-1B. A cousin has a TN. A friend from Sydney has an E-3. None of that tells you which category you are actually in, or whether your current status can lead to a green card.
Two key questions matter most: Is the visa capped and subject to a lottery? And can you apply for a green card without putting your current status at risk?
This guide compares the major U.S. work visa categories based on these questions, along with stay limits and eligibility requirements.
Read the explanation under your row before making any decisions, as some of these visas have special requirements;
The H-1B is what most people picture when they hear "work visa." An employer files on your behalf, you need a bachelor's degree or its equivalent in a specialty occupation, and if the category is capped for the year, your case enters a weighted lottery before USCIS even looks at it.
The cap is 85,000 a year (65,000 under the regular cap, plus 20,000 reserved for holders of a U.S. master's degree), and total time on H-1B status is 6 years. You can pursue a green card while holding H-1B status without jeopardizing it.
For the full mechanics of the lottery and current processing timelines, see our H-1B processing time guide and our LCA for H-1B guide.
Both L-1 categories move an employee from a company's foreign office to its U.S. operation, and both require one continuous year working abroad for the same corporate group in the three years before filing. Neither has an annual cap or a lottery.
The split is capacity and duration. L-1A is for managers and executives and allows up to 7 years. L-1B is for employees with specialized company knowledge and allows up to 5 years. You can pursue a green card on both statuses without risking your status. However, L-1A naturally pairs with the EB-1C category for multinational executives in a way L-1B doesn't.
See our L-1A guide and L-1B guide for the full eligibility tests.
The O-1 is for individuals with extraordinary ability or achievement in their field. It carries no annual cap, no lottery, and no registration window. So you can file your petition at any point in the year.
The O-1 is initially valid for up to 3 years, and extensions come in 1-year increments with no statutory limit on how many you can file. You can pursue a green card while holding O-1 status without risking it.
Our O-1 visa guide covers the evidentiary requirements in full, including the split between the O-1A and O-1B subcategories.
The TN category exists only for Canadian and Mexican citizens, and only for a defined list of professions set out under the USMCA. There is no annual cap and no lottery.
Each period of stay runs up to 3 years, and you can renew TN status indefinitely with no absolute maximum. However, TN holders must maintain nonimmigrant intent, meaning you cannot pursue a green card without risking future renewals.
TN dependents don't automatically receive work authorization. Canadian citizens can apply directly at a port of entry; Mexican citizens need a visa first.
The E-3 is a treaty visa limited to Australian citizens, working in a specialty occupation under a standard similar to H-1B's. It has its own annual cap of 10,500, which has in practice never been reached.
Each period of stay runs up to 2 years and can be renewed indefinitely, with no stated maximum. Like TN, E-3 requires strict nonimmigrant intent. Meaning you cannot pursue a green card. You must show an unequivocal intent to depart once your E-3 status ends.
The good side, however, is that E-3 spouses are eligible for their own independent work authorization. TN spouses are not.
H-2A and H-2B visas require workers to be citizens of designated countries, with few exceptions. H-2A is for temporary agricultural work, while H-2B covers temporary non-agricultural work that is seasonal or peak-load.
H-2A has no annual cap, whereas H-2B is capped at 66,000 visas per year. Both categories tie workers to a specific job and employer, are approved for about a year at a time, and do not provide a direct path to a green card.
These categories serve a different focus. If you are a professional evaluating options like H-1B, TN, E-3, L-1, or O-1, H-2 visas likely do not apply to you.
The R-1 visa allows religious workers, including ministers and individuals working in a religious vocation or occupation, to temporarily perform religious work in the U.S.
To qualify, you must have been a member of a bona fide nonprofit religious denomination in the U.S. for at least two years immediately before filing. The visa allows an initial stay of up to 3 years, which can be extended for a total maximum stay of 5 years.
The P-1 covers individual and team athletes, members of entertainment groups, and essential support personnel. Unlike most categories in this guide, P-1 status is tied to a specific competition, event, or performance, not an open-ended employment relationship.
A few other categories fall outside this main comparison. Q-1 is for international cultural exchange visitors in structured programs. E-1 and E-2 cover treaty traders and investors, which we explain in our E-2 visa guide along with their nationality rules.
Each of these categories has a limit. H-1B ties you to winning a lottery. TN, E-3, and H-2 tie you to a specific nationality. All of them tie you to a specific employer, and TN and E-3 also require you to maintain nonimmigrant intent.
If you don't fit one of those boxes, or you fit one but don't want your status to depend on a nationality, a lottery outcome, or a single employer, an O-1 or EB-2 NIW self-petition is worth a look. Neither has an annual cap, and neither ties your status to any one company staying in business or one employer willing to sponsor you.
This doesn't mean either category is faster. Several of the categories compared above, TN and E-3 especially, have no backlog or lottery of their own. So the real difference is that you are not dependent on an employer.

H-1B is open to any nationality but is capped and lottery-based. TN and E-3 are open only to Canadian/Mexican and Australian citizens, but have no cap or lottery. H-2 is open only to designated-country nationals doing temporary agricultural or non-agricultural work. The R-1 is for religious workers and doesn't depend on nationality.
H-1B, L-1, and O-1 permit dual intent, meaning you can pursue a green card on these visas. In contrast, TN and E-3 require you to prove nonimmigrant intent, so you cannot pursue a green card.
Neither is categorically better. TN has no cap and no lottery, but it is limited to Canadian and Mexican citizens in specific professions, and it does not support a green card plan without risk. H-1B is open to any nationality and supports a green card plan safely, but entry depends on winning the lottery.
Yes. The E-3 is a treaty category limited to Australian citizens. Its separate annual cap of 10,500 has, in practice, never been reached.
H-2A covers temporary agricultural work. H-2B covers temporary non-agricultural work of a seasonal or peak-load nature. Both require the worker to hold citizenship or nationality from a designated country, and both tie the worker to a specific employer and job.
It depends on the category. E-3 spouses are eligible for independent work authorization directly. Spouses and dependents of H-1B, L-1, and O-1 holders may become eligible for work authorization under certain circumstances tied to the primary holder's status. TN spouses do not automatically receive work authorization.
