Employers usually ask which visa is fastest. The better question is which category the job and the person honestly fit, because a case built on the wrong category is slow in the way that matters: it fails.
H-1B
For a specialty occupation, meaning a role that normally requires at least a bachelor's degree in a specific field, filled by someone who holds that degree or its equivalent. The constraint is not the standard, it is the supply: most new H-1B petitions are subject to an annual cap and a registration process that runs once a year, so timing is dictated by a calendar rather than by the business. Universities and certain non-profit research employers are outside the cap.
L-1
For moving someone inside the same corporate group: an executive or manager, or an employee with specialized knowledge, who has worked for a related company abroad for at least one continuous year in the preceding three. No annual cap. The case turns on proving the corporate relationship and the substance of the role, not on a degree.
TN
For Canadian and Mexican professionals in occupations listed under the trade agreement, working for a U.S. employer in that profession. It is comparatively quick and comparatively narrow: if the occupation is not on the list, there is no argument to be made, and TN is a temporary status that does not sit comfortably alongside an intention to remain permanently.
E-2
For a national of a treaty country investing a substantial amount in a real, operating U.S. business they will direct, and for certain employees of that business. What counts as substantial is relative to the business rather than a fixed figure. The status can be renewed for as long as the business qualifies, and it does not lead to a green card by itself.
O-1
For extraordinary ability, which in practice means sustained recognition evidenced by a defined list of criteria: awards, press, high salary, critical roles, commercial success. In music and entertainment it is the workhorse category, and the evidence is the case. No cap, but it is documentation-heavy and tied to specific work.
The employment green card
Separate track, usually beginning with a labor market test and ending with adjustment of status or a consular interview, and gated by priority dates that vary sharply by country of birth. A worker can be on a temporary visa for years while the permanent case proceeds, and the two have to be sequenced deliberately.
What changed for students
In 2026 the Department of Homeland Security ended duration of status admission for F-1 and J-1 nonimmigrants and replaced it with a fixed period of admission. For a student moving into a work category, the admit-until date on the current I-94 now matters directly, because overstaying a fixed date carries consequences that the old system did not impose in the same way.
The question to settle first
Before choosing a category, settle whether the person intends to stay permanently. Some of these categories tolerate that intention and some do not, and it is far cheaper to plan for it at the start than to explain it at a consulate later.
