IN THIS GUIDE · Distinguish prior consulting work from the qualifying employment history
Start with the L-1B eligibility and application overview
Identify the actual working arrangements over time
Hypothetical example: the applicant provided services through an outside business before accepting employment with the proposed transferring company. Record the entities, dates, supervision and actual work at each stage. Have the nature of each period assessed rather than adding all years of association together. List the periods in reverse, most recent first, and stop once three years have been covered, since the relevant employment is measured within the three years preceding the filing or admission. Earlier periods still belong in the history, but they are context rather than the year being tested.
Separate acquired knowledge from employment qualification
Explain what the applicant learned, when it was applied and how the proposed U.S. duties use special or advanced organizational knowledge. That explanation does not replace the foreign employment requirement. A strong project history and a qualifying employment period are related evidence questions, not interchangeable conclusions. Note also which of these two showings can be improved later and which cannot. The description of specialized knowledge can be redrafted, expanded and supported with further examples at any point before filing. The employment period cannot be added to retroactively, so it is the constraint the schedule should be built around.
Use original records without rewriting the earlier relationship
Provide relevant agreements, payment records and evidence of actual responsibilities for professional assessment. Explain changes and inconsistencies openly. Do not relabel earlier consulting work as employment merely to meet a desired transfer date, or assume the label alone determines its legal treatment. Where a document has already gone out carrying an inaccurate label, do not withdraw and reissue it silently. Keep the original, add a dated explanation of what it should have said, and let counsel decide how the discrepancy is presented. A replaced document that leaves no trace is the version that becomes difficult to explain.
Assess the proposed transfer using the established history
Identify the actual foreign employer, qualifying company relationship and relevant employment period, including work locations. The general continuous-year requirement must be assessed within the applicable timeframe on the individual facts. Do not assume a new contract or planned promotion retroactively supplies an earlier qualifying period. Add the intended worksite to that assessment early. L-1B placement principally at a third party's worksite is restricted where the work is controlled by the other employer or amounts essentially to labour for hire, and a placement arranged after the file has been built may not be easy to rearrange once a customer has been promised a start date.
The end of the consulting relationship is the date that must be provable
Two dates decide most of these files and only one of them is usually documented. The first is the day the applicant stopped supplying services through an outside business; the second is the day employment with the qualifying organisation began. Where an invoice run simply tapers off while a salary begins in the same period, the boundary has to be reconstructed afterwards from whatever happens to survive, and reconstruction is what a reviewer treats with the most caution. Hypothetical example: a packaging-line installer keeps issuing occasional invoices for six months after joining the payroll of the company that will sponsor the transfer, and the continuous year is now contested at both ends. Set the boundary while it can still be set: a dated termination of the services agreement, a first payroll deposit, an employment contract signed before the work changed. Once a transfer plan exists, any document created to clarify that boundary will be read as having been created for the plan, which is a weaker record than one made at the time.
