IN THIS GUIDE · Review a returning employee’s earlier knowledge and qualifying employment separately
Start with the L-1B eligibility and application overview
Build a dated account of the two employment periods
Identify the employer entities, actual work abroad, any interval outside the organization and the current position. Generally a continuous year of qualifying full-time foreign employment within the relevant preceding three years must be established. Do not assume separate periods can simply be added together to create a continuous year.
Explain what the employee knows now
Describe special knowledge of organizational interests and international application, or advanced knowledge of organizational processes and procedures. Identify what changed during the employee’s absence and what has been refreshed since returning. Past familiarity should not be portrayed as complete knowledge of processes introduced while the person worked elsewhere.
Connect the current assignment to the qualifying group
Document the parent, branch, affiliate or subsidiary relationship and continuing qualifying business in the United States and abroad. A familiar brand does not prove that the earlier and current employers are the same qualifying organization. Explain the proposed U.S. duties and the person’s actual preparation for them.
Which record fixes each employment period
Rehire cases turn on dates, and dates are asserted in several documents that were never meant to agree. An employment agreement fixes what was promised; a payroll or social-security record fixes what was paid; a record of employment or separation letter fixes when the relationship ended. Where these diverge, the payroll record generally carries the most weight for continuity, because it reflects performance rather than intention, while the agreement explains the terms behind it. Ask the employer for both, in the employer's own format, rather than a human-resources summary prepared for this file. A summary written after the fact is the weakest document in the folder, and it is usually the one that introduced the inconsistency in the first place.
The two mistakes rehire files repeat
The first mistake is arithmetic dressed as continuity: adding a seven-month period before the departure to a five-month period after the return and calling the result a year. Continuity is a property of a single unbroken period of qualifying employment, not a total. The second is describing knowledge in the present tense that was acquired in the past. Processes change while someone is away, and a file claiming current advanced knowledge of a procedure introduced during the absence will not survive a question about when and how the person learned it. Say what was known before, what changed, what has been relearned since the return, and by what means.
State the relationship and the maximum period
Two conditions frame every rehire proposal and both should appear in the file rather than being assumed. The qualifying organization must stand in a parent, branch, affiliate or subsidiary relationship to the United States entity, and that relationship must be shown with corporate documents rather than shared branding; groups reorganise, and the entity that employed someone four years ago may not be the entity that qualifies today. The second condition is duration: L-1B is subject to a five-year maximum, and time already spent in L status counts toward it. Someone who previously held L status therefore has a shorter runway than a first-time transferee, which affects whether a shorter assignment is worth the process at all.
