L1A or L1B: which visa fits your company

The question "do we need L1A or L1B" almost always comes up late — after the company has already decided to transfer an employee to the US and started gathering documents. By that point the category choice should already be settled: it decides not just the form of the petition, but what evidence needs to be gathered and how long the employee can stay in status.

The difference between the categories is not about prestige or how hard the filing is. It comes down to one concrete question: what does the person actually do in the company.

The shared foundation for both visas

L1A and L1B are one visa category for intracompany transfers, split into two subtypes. They share the same base requirements.

The US company and the foreign company must be in a qualifying relationship: parent and subsidiary, branch, or affiliated entities under common ownership or control. An informal cooperation agreement or a franchise does not qualify — what is needed is an actual corporate link.

The employee must have worked continuously for the foreign company for at least one year within the three years preceding the transfer, and that work must have been in the same type of role as the one they are transferring into — managerial, executive, or specialized-knowledge. A year of work "somewhere in the company" in a different type of role does not meet this requirement.

From here the two categories diverge, and they diverge specifically over what the position actually involves.

L1A: a managerial or executive position

L1A is built for people who manage an organization, a department, a function, or a team of specialists — who make decisions rather than carry out individual tasks. That can be a branch director, the head of a function, or an executive setting strategy, even with a small number of direct reports.

The key question here is not "how many people report to this person" but "who makes the decisions." A small team where the manager holds real managerial authority is more defensible than a formal "director" title with no authority to hire, fire, or control a budget.

L1B: specialized knowledge

L1B is built for an employee whose knowledge of the company's product, processes, or methods clearly exceeds the ordinary level in the industry and is hard to hand off to someone else quickly. This is not a general qualification like "experienced engineer" — it is knowledge tied specifically to this company: how a particular product, technology, or internal process works.

This is the most contested criterion in the whole category: "specialized" and "ordinary for the industry" are not separated by a hard line, and this is where additional evidence is most often requested. What helps is not a general description of the employee's experience but concrete examples: what this person is the only one, or one of very few, able to do in the company, and what happens if that knowledge is not present in the US.

Different maximum periods of stay

The categories also differ in how long an employee can stay in status. For an employee transferring into an office that is already up and running, the initial period is up to three years. After that, status is extended in increments of up to two years, until the overall cap is reached: seven years for L1A and five years for L1B. That two-year difference matters if the company is planning not a one-off transfer but years of a manager's work in the US.

Once that cap is used up, returning to L1 status requires having worked outside the US for at least a year first — so the overall time limit is worth spending deliberately, not on a position the employee is expected to outgrow sooner.

Opening a new office — a separate set of requirements

If the transfer is into a company that has just been formed or is not yet operating in the US, a separate set of requirements is added: the petition has to show that the business has enough premises and resources to begin operating, and that within a foreseeable period it will be able to support the position the employee is transferring into. This is not an alternative to the core L1A or L1B criteria — it is an additional layer on top of them.

For new offices, the initial period of stay is shorter than for an already-operating company — one year instead of three. Within that year the business has to show it is actually up and running and able to support the position, so it is especially important from the start to build the documentation so that the later extension does not turn into a fresh petition built from scratch.

Deciding when an employee fits both criteria

Sometimes a position formally combines a managerial role with specialized knowledge — for example, a manager who is also the sole holder of a key technology. In that situation the choice is not made on a formal basis, but on which claim is better supported by the documents already available: an organizational structure and a team of subordinates argue for L1A, concrete examples of unique expertise argue for L1B.

Mixing both justifications in a single petition usually does not help: the result is a document that half-proves one thing and half-proves another, and fully proves neither. The category should be chosen once, before the package is put together, not partway through assembling it.

What to check before filing

The companies are in a documented qualifying relationship, not just a working partnership. The year of foreign employment is backed by documents and is in the same type of role the employee is transferring into. For L1A, it is clear who actually makes the decisions, not just what the title says. For L1B, there are concrete examples of unique knowledge, not just a general level of experience. If the company is opening a new US office, there is separate evidence prepared showing it will be able to support the position.

Choosing between L1A and L1B is rarely difficult once the position is described honestly. The difficulty starts when the category is picked for how it sounds rather than for what the documents can actually prove.
