L1 Visa Requirements: Complete UK Guide for 2025

The L1 visa requirements present a viable pathway for UK professionals seeking to transfer to a US office within their multinational company. Unlike the H1B visa lottery, the L1 has no annual cap. However, approval is never guaranteed, and USCIS applies strict eligibility standards that result in significant denial rates, particularly for L1B petitions.

This guide covers everything UK-based employees and employers need to know about L1 visa eligibility, costs, processing times, and the application process. For an overview of the L1 visa program, see our complete L1 visa guide.

What Is the L1 Visa?

The L1 visa is a non-immigrant work visa that allows multinational companies to transfer employees from foreign offices to US offices. USCIS classifies it as an intracompany transferee visa, designed for executives, managers, and workers with specialized knowledge (USCIS, July 2024).

Think of the L1 as an internal company bridge. Rather than hiring externally in the US, companies move existing talent across borders to fill critical roles.

Key features of the L1 visa:

  • No annual numerical cap
  • Dual intent permitted (you may pursue a green card)
  • Dependents receive L2 visas with work authorisation
  • Available year-round without lottery

The L1 visa comes in two categories: L1A for executives and managers, and L1B for specialized knowledge workers. Each has different validity periods and green card pathways.

L1A vs L1B Visa: Key Differences

FeatureL1A (Executive/Manager)L1B (Specialized Knowledge)
Role TypeExecutive or managerial capacitySpecialized knowledge of company products, services, or procedures
Maximum Stay7 years5 years
Initial Validity1-3 years1-3 years
Green Card RouteEB-1C (no PERM required)EB-2 or EB-3 (PERM required)
Scrutiny LevelModerateHigh — USCIS applies strict interpretation
Denial RateLowerHigher — specialized knowledge claims face significant challenges

The L1A offers a more straightforward path to permanent residence through the EB-1C category, which does not require labor certification. L1B holders face a longer green card process and must navigate the PERM labor certification system.

USCIS has historically scrutinized L1B petitions more heavily. The agency's 2015 policy memo tightened the definition of "specialized knowledge," leading to increased denials (USCIS Policy Memorandum, March 2015). Applicants should prepare thorough documentation demonstrating why their knowledge is genuinely specialized and not simply skilled.

L1 Visa Requirements for Employees

To qualify for an L1 visa, employees must meet specific criteria related to their employment history and job role.

Prior Employment Requirements

The core requirement: you must have worked for the qualifying foreign company for at least one continuous year within the three years immediately before your US transfer (USCIS, July 2024).

  • Employment must be full-time
  • The year must be continuous (no breaks)
  • Part-time work does not count toward the one-year requirement
  • The role abroad must be in an executive, managerial, or specialized knowledge capacity

If you left the company and returned, the one-year clock restarts. Brief business trips to the US during your qualifying year generally do not interrupt continuity, but extended US assignments may cause complications.

Qualifying Roles and Positions

Your role must fall into one of three categories:

Executive capacity — You direct the management of the organisation or a major component. You establish goals and policies, exercise wide latitude in decision-making, and receive only general supervision from higher executives or the board.

Managerial capacity — You manage the organisation, a department, or a function. You supervise and control the work of professional employees or manage an essential function. First-line supervisors do not qualify unless they supervise professionals.

Specialized knowledge — You possess advanced knowledge of the company's products, services, research, equipment, or processes that is not widely held in the industry. Alternatively, you have advanced knowledge of the company's procedures that is distinct from general industry knowledge.

The specialized knowledge category causes the most denials. USCIS requires evidence that your knowledge is truly special to your company, not simply expert-level skills available in the US labor market.

L1 Visa Requirements for Employers

The petitioning US company must also meet strict requirements.

Qualifying Company Relationships

The US entity and foreign entity must have a qualifying relationship. Acceptable relationships include:

  • Parent company and subsidiary
  • Subsidiary and parent company
  • Affiliate companies (common ownership or control)
  • Branch offices of the same company

Both entities must be doing business. A shell company or dormant entity does not qualify. USCIS will examine ownership structures, financial records, and operational evidence.

Active Business Requirements

Both the US and foreign companies must be actively conducting business throughout the duration of the L1 holder's stay (USCIS, July 2024). This means:

  • Regular, systematic, and continuous provision of goods or services
  • Physical premises in both countries
  • Employees and operational infrastructure
  • Mere presence of an agent or office does not suffice

For new US offices, companies may petition for an L1 visa to send an employee to establish operations. However, these "new office" petitions receive only a one-year initial approval period, and the company must demonstrate significant progress at extension time.

Blanket L1 Petitions

Large multinational companies may qualify for blanket L1 status, which streamlines the process for frequent transfers. Requirements include:

  • The petitioner and qualifying organisations are engaged in commercial trade or services
  • The petitioner has a US office that has been doing business for one year or more
  • The petitioner has three or more domestic and foreign branches, subsidiaries, or affiliates
  • The petitioner and qualifying organisations have obtained at least 10 L1 approvals in the past 12 months, OR have US subsidiaries or affiliates with combined annual sales of at least $25 million, OR have a US workforce of at least 1,000 employees

L1 Visa Documents Required

Employee Documents

  • Valid passport (at least six months validity beyond intended stay)
  • DS-160 confirmation page
  • Visa application fee payment receipt
  • Form I-797 approval notice (or I-129S for blanket petitions)
  • Passport-style photograph meeting US visa requirements
  • CV or resume detailing employment history
  • Evidence of one year qualifying employment abroad
  • Job offer letter describing US role and responsibilities
  • Organisational charts showing position in both entities
  • Letters from supervisors describing your role and specialized knowledge

Employer Documents

  • Form I-129 petition (individual) or I-129S (blanket)
  • Evidence of qualifying relationship between entities
  • Financial documents (tax returns, annual reports, audited accounts)
  • Business registration documents for both entities
  • Lease agreements or property ownership evidence
  • Organisational charts
  • Evidence of employees and ongoing operations
  • For new offices: business plan, evidence of premises, proof of sufficient funding

L1 Visa Application Process from the UK

The L1 visa application follows these steps:

  1. Employer files Form I-129 with USCIS — The US company submits the petition with all supporting documentation. For blanket petitions, the employer files Form I-129S instead.
  2. USCIS adjudicates the petition — Processing takes 2-6 months for standard cases. Premium processing (15 calendar days) is available for an additional fee.
  3. Receive I-797 approval notice — Once approved, USCIS sends the approval notice to the employer.
  4. Complete DS-160 online — The employee fills out the nonimmigrant visa application form and uploads a photograph.
  5. Pay the visa application fee — Currently $185 for L1 visas (U.S. Department of State, 2024).
  6. Schedule visa interview — Book an appointment at the US Embassy in London or the US Consulate in Belfast.
  7. Attend visa interview — Bring all required documents. Interviews typically last 5-15 minutes.
  8. Receive visa — If approved, your passport with the visa stamp is returned within 5-10 business days.

Note: Blanket L1 applicants may have their interviews waived in some circumstances, but this is not guaranteed.

L1 Visa Interview Questions

US consular officers assess whether you meet the L1 requirements. Common questions include:

  • What is your current role and what will you do in the US?
  • Describe your company's relationship between the UK and US offices
  • How long have you worked for the company?
  • What specialized knowledge do you have?
  • Who will you report to in the US?
  • How many people will report to you?
  • What is the purpose of your transfer?

Preparation tips:

  • Review your petition documents thoroughly
  • Be ready to explain your role in simple terms
  • Bring organisational charts and evidence of the company relationship
  • For L1B applicants, prepare to articulate what makes your knowledge specialized
  • Answer directly and honestly — consular officers are trained to detect inconsistencies

Denials at the interview stage are less common than petition denials, but they do occur. If the officer has concerns about your eligibility, they may request additional documentation or issue an administrative processing delay.

L1 Visa Validity and Extensions

Initial Validity Periods

  • Individual L1 petition (existing US office): Up to 3 years
  • Blanket L1 petition: Up to 3 years
  • New office petition: 1 year only

Maximum Stay

  • L1A: 7 years total
  • L1B: 5 years total

Extensions

You may apply for extensions in two-year increments until you reach the maximum. Extensions require a new Form I-129 petition demonstrating continued eligibility.

After reaching maximum stay, you must remain outside the US for at least one year before qualifying for a new L1 visa, unless you have obtained a green card or changed to another status.

L1 Visa to Green Card Pathway

The L1 visa permits dual intent, meaning you may pursue permanent residence while holding L1 status.

L1A to Green Card (EB-1C)

L1A holders may qualify for the EB-1C multinational manager or executive green card category. Key advantages:

  • No PERM labor certification required
  • Faster processing than EB-2 or EB-3
  • No job posting or recruitment testing needed

The employer files Form I-140 directly. Current processing times for EB-1C vary by USCIS service center but typically range from 6-18 months (USCIS, 2024).

L1B to Green Card (EB-2 or EB-3)

L1B holders must pursue the EB-2 or EB-3 categories, which require:

  • PERM labor certification (employer tests the US labor market)
  • Form I-140 immigrant petition
  • Adjustment of status or consular processing

The PERM process alone takes 8-18 months. For UK nationals, visa backlogs are minimal, but total processing from PERM to green card often exceeds 2-3 years.

Risks and limitations:

  • L1B holders on five-year maximum may run out of time before completing the green card process
  • PERM denials can reset the timeline
  • Company must remain willing to sponsor throughout
  • Economic downturns may lead to layoffs that terminate sponsorship

L1 Visa vs H1B: Which Is Better?

FactorL1 VisaH1B Visa
Annual capNone85,000 (lottery system)
Employer requirementMust work for multinational with qualifying relationshipAny US employer; no prior relationship needed
Prior employmentOne year with foreign affiliate requiredNo prior employment requirement
Job portabilityLimited to petitioning employerCan transfer to new H1B sponsor
Maximum stay5 years (L1B) or 7 years (L1A)6 years (extendable with green card pending)
Green card pathL1A: EB-1C (faster); L1B: EB-2/EB-3EB-2 or EB-3 (PERM required)
LotteryNoYes — approximately 25% selection rate

Neither visa is universally better. The L1 suits employees of multinationals seeking predictable transfers without lottery risk. The H1B offers more flexibility for job changes but comes with significant lottery uncertainty.

FAQs About L1 Visa Requirements

Is the L1 visa difficult to get?

Difficulty varies by category. L1A petitions for executives and managers have moderate approval rates when well-documented. L1B petitions face higher scrutiny, and denial rates have increased since USCIS tightened specialized knowledge standards in 2015. Strong documentation and clear evidence of qualifying criteria improve success rates.

How many years is the L1 visa valid?

The L1A visa allows a maximum stay of seven years. The L1B visa allows a maximum of five years. Initial approvals range from one to three years depending on the petition type, with extensions available in two-year increments.

What is needed for an L1 visa?

Employees need one continuous year of qualifying employment abroad within the past three years, plus a job offer in an executive, managerial, or specialized knowledge role. Employers need a qualifying relationship between the US and foreign entities, active business operations in both countries, and proper petition documentation.

Is the L1 visa easier than the H1B?

The L1 avoids the H1B lottery, making it more predictable for eligible candidates. However, L1 eligibility requirements are stricter — you must have worked for the company abroad and the company must have qualifying foreign operations. Neither visa is inherently easier; each suits different circumstances.

Can L1 visa holders change employers?

No. The L1 visa is tied to the petitioning employer. Changing employers requires a new visa petition from the new employer, and the new employer must have a qualifying relationship with a foreign entity where you previously worked for one year. In practice, most L1 holders cannot simply switch to a different company.
