L-1B Intracompany Specialized Knowledge

Requirements

• The U.S. and foreign companies must be parent, branch, subsidiary or affiliate.
• You worked for the foreign company 1 continuous year within the 3 years before entry.
• You have special or advanced knowledge of the company's products, processes or procedures.
• If placed at another company's site, you can't be controlled by that company or be 'labor for hire'.
• New office: secured premises and the money to pay you and start business.

How long you can stay

New office: up to 1 year at first; others: up to 3 years. Extensions come in up to 2-year steps, to 5 years in total (time in H-1B counts too).

Timeline

Regular USCIS processing for L petitions is about 6.5 months (80% of cases); premium processing gives action within 15 business days. Blanket L cases skip USCIS and go straight to the Embassy. Seoul interview waits were under half a month as of Sep 17, 2026. Check current times.

Government fees

Most L fees are the employer's. Blanket L cases at the Embassy may also owe the $4,500 Pub. L. 114-113 fee if the employer is covered.

Typical attorney fees

One online flat-fee firm lists $8,000 for a new or new-office L-1 and $3,000 for an extension. Many employers cover these costs.

Spouse & children

Spouse and unmarried children under 21 can get L-2 with the same stay. Spouses with an L-2S I-94 can work incident to status; an EAD is optional.

Work

You may work only for the petitioning company. Moving to an unrelated employer needs a different status, such as H-1B.

Path to a green card

EB-1C is for managers and executives, so L-1B workers more often explore employer-sponsored EB-2 or EB-3 (PERM).

Note for Korean applicants

Korean companies with a related U.S. company can transfer specialized staff on L-1B. For Koreans, L visas are issued with no reciprocity fee, multiple entries, for up to 60 months. Interviews are at the U.S. Embassy in Seoul.

Key documents

• Proof of the corporate relationship (ownership records, org chart)
• Proof of 1 year of work abroad (employment letter, payroll)
• Letter explaining your specialized knowledge and how you gained it
• Offsite placement: proof the petitioner keeps control of your work
• I-797 approval or Form I-129S (blanket L) for the interview

Common pitfalls

• General skills common in the industry usually don't count as specialized knowledge.
• Under a blanket L, an L-1B worker must also be a professional.
• After 5 years in L-1B, you must live abroad 1 year before new L or H status.
• Covered employers now pay the $4,500 9-11 fee on extensions too (since Sep 9, 2026).
• After a job loss, the 60-day grace period is short, and a proposal would remove it.
