Quick answer: The L-1B visa lets a company transfer an employee with specialized knowledge from a foreign office to a related US office. Like the L-1A, it generally requires one continuous year of employment abroad within the last three years and a qualifying relationship between the two companies.

If you work for a multinational and your value lies in deep knowledge of the company’s products, tools or processes rather than in managing people, the L-1B visa is the category to look at. This guide covers what it is, who may qualify and how it differs from the manager and executive version.

What is the L-1B visa?

L-1B is the specialized knowledge branch of the L-1 intracompany transferee classification. The US employer petitions for an employee who has worked for a related foreign entity and who will use specialized knowledge in the United States. The manager and executive version is explained in our L-1A visa guide.

Eligibility at a glance

Requirement What it means
Qualifying relationship The foreign and US employers must be related, such as parent, branch, subsidiary or affiliate.
Prior employment One continuous year of work for the foreign entity within the last three years.

L-1A vs L-1B

Point L-1A L-1B
Who it is for Executives and managers Employees with specialized knowledge
Focus of the petition Management or executive duties The nature of the specialized knowledge
One-year rule Yes Yes
Company relationship Required Required

How to prepare a strong case

  1. Document the corporate relationship between both entities.
  2. Show the employee’s continuous year of work abroad.
  3. Explain exactly what the specialized knowledge is and why it is not common in the field.
  4. Connect that knowledge to the US job duties.

Fee alert

USCIS has posted an alert about a Biometric Fee final rule effective September 9, 2026 for H-1B and L-1 petitions by covered employers. Check the current USCIS fee information before you file.

Common mistakes

  • Describing knowledge too vaguely. Say specifically what it is and how it was gained.
  • Missing the one-year window. The year must fall within the last three years.
  • Weak proof of the company link. Include ownership and control evidence.

Frequently asked questions

Can I switch from L-1B to L-1A later?

A change in role would need to be supported by the facts and, where required, a new filing. Ask an immigration attorney about your case.

Do I need a degree for the L-1B?

The USCIS page frames the test around specialized knowledge and the company relationship rather than a specific degree.

Key takeaways

  • L-1B is for specialized knowledge employees moving within a company group.
  • A year of employment abroad in the last three years is the usual rule.
  • Clear evidence of what makes the knowledge specialized is critical.
