Expanding operations into the United States is a natural step for many UK companies, especially in sectors like technology, engineering, and consultancy.
The L1B visa, designed for specialized knowledge employees, is a valuable immigration tool to facilitate this. However, despite its strategic potential, many UK businesses make avoidable errors during the L1B application process — errors that can result in delays, denials, or compliance risks.
At Corporate Visa Solutions (CVS), we regularly advise UK businesses on how to avoid the most common L1B visa mistakes and ensure every application is aligned with USCIS expectations.
Common L1B visa mistakes UK companies make
The most frequent L1B visa mistakes often stem from misunderstandings about the “specialized knowledge” requirement. UK employers may assume that simply being experienced or highly trained is enough — but U.S. immigration authorities expect detailed proof that the knowledge is both proprietary and essential to the business.
Other common errors include:
- Poor documentation of the employee’s qualifications and role within the UK entity.
- Insufficient detail on the U.S. job description and why it requires that specific employee.
- Lack of internal consistency across forms, letters, and supporting materials.
- Incorrect corporate relationships, especially when sending employees from UK affiliates that don’t meet the qualifying criteria.
For a broader look at visa options for UK-based companies, CVS provides this detailed guide to visas for the United States.
How to apply for L1B visa without falling into the usual traps
Understanding how to apply for an L1B visa correctly starts with knowing what USCIS is looking for. A successful petition should clearly demonstrate:
- The qualifying relationship between the UK and U.S. entities (e.g., parent, subsidiary, branch).
- That the employee has been working at least one continuous year outside the U.S. within the last three years in a role requiring specialized knowledge.
- A detailed job description showing why that knowledge is essential to the U.S. role.
- Robust evidence such as org charts, training manuals, and project documents to support the employee’s expertise.
Corporate Visa Solutions ensures your documentation meets these expectations from day one, reducing the risk of RFEs or denials.
L1B applications: Fixing mistakes before they become problems
Once submitted, L1B applications often attract Requests for Evidence (RFEs) if there are doubts about eligibility or insufficient supporting documentation. CVS helps clients proactively address these weak spots through:
- Pre-assessment audits to spot gaps before filing.
- Ensuring terminology and evidence are consistent throughout all forms and exhibits.
- Providing tailored guidance based on the structure of your UK and U.S. operations.
We also assist clients with L1 Blanket Petitions when scaling is a priority and multiple employees need to be transferred in a streamlined way.
