IN THIS GUIDE · Document the specialized-knowledge assignment after a new office begins operating
Start with the L-1B eligibility and application overview
Identify how the assignment developed in practice
Hypothetical example: an employee initially configured internal processes and now applies that knowledge in ongoing service delivery. Explain the actual current duties and the organizational knowledge they require. Do not repeat completed setup tasks as though they remain the entire future assignment. Hypothetical example: A heritage-sound archive software firm first sent an employee to configure its metadata rules, then assigned that employee to solve unusual customer migrations. The decision is whether the current work still uses advanced organizational knowledge. Demonstrations, internal training records, and task examples are more informative than a recycled launch description.
Show that the business actually operates
Identify appropriate evidence of regular, systematic and continuous provision of goods or services. A new-office petition is initially limited to no more than one year, after which the petitioner must demonstrate doing business for an extension. A registered entity and retained premises alone do not establish that activity. A first review should tie each claimed service to a dated customer or internal operating record. Order confirmations, delivery logs, support tickets, and invoices may show regular activity in different ways. Select records that identify the U.S. entity’s role; a supplier’s activity or an empty office does not prove that this petitioner is doing business.
Explain knowledge used in continuing duties
Select genuine examples showing the employee’s special or advanced organizational knowledge and present use. The fact that a launch is complete does not answer whether the later role meets L-1B requirements. Describe changes, retained responsibilities and any planned work that has not yet begun. Describe the knowledge at the right level of detail: what the employee understands, how it was acquired, why it is uncommon or advanced in the organization, and how the U.S. duties use it. Avoid confidential formulas where a functional description will do. The file should make a reviewer able to compare the knowledge claim with actual assignments.
Keep the L-1B and L-1A analyses distinct
L-1B does not require the applicant to become a manager simply because the first year ends. The actual knowledge role and other applicable requirements still need assessment. If the employee is instead moving into a different capacity, have that change reviewed rather than silently substituting a new title in the extension evidence. If the later role now includes ordinary production work, separate that work from the specialized function instead of assuming a prestigious title answers the issue. The company must decide what capacity it is asking to have assessed. A change in duties can be material even when the employer, location, and payroll remain the same.
Ask whose product or process the knowledge concerns
Explain the applicant’s work on the relevant product or process, what was learned and how that knowledge is applied.
