IN THIS GUIDE · Auditing the qualifying year of foreign employment
Start with the L-1B eligibility and application overview
Build one employment and travel chronology
Record employment start and end dates, legal employers, work locations and trips to the United States. The general framework requires a continuous qualifying year abroad within the relevant three-year period. Travel and prior U.S. employment can affect the analysis; a payroll anniversary does not by itself establish the required time abroad.
Identify the capacity during that year
The qualifying foreign work must have been managerial, executive or specialised knowledge employment. The foreign and U.S. capacities need not be identical, but the record must establish the qualifying duties abroad and the specialised-knowledge position now proposed. Promotions and title changes should be explained with dates and actual responsibilities.
Reconcile employer names
Payroll, contracts and tax records may use different legal entities or trading names. Explain those differences and document the qualifying relationship rather than assuming a shared brand is enough. Where employment moved between group entities, identify the sequence and supporting records. An unexplained name change can obscure an otherwise understandable history.
Resolve gaps before setting a start date
Identify missing pay periods, extended absences, contractor periods and prior U.S. work for individual review. Do not quietly count every calendar day as foreign employment. A transparent chronology lets counsel assess the applicable rules and any adjustments. Strong technical expertise cannot compensate for an unmet employment prerequisite.
Fix the three-year window before counting anything
The requirement is not simply a year of service somewhere in the past; it is generally a continuous year of qualifying employment abroad within the three years preceding the filing or the admission. That makes the window the first thing to establish, because it determines which period is even relevant. Fix the anticipated date, count back three years, and mark the boundary. Then lay the employment history against it. A year completed four years ago falls outside and does not assist, however substantial it was. A year that straddles the boundary needs examining carefully. Where the intended filing date is uncertain, model more than one, since a delay of a few months can move the window past a period the case depends on. Doing this arithmetic first prevents a great deal of evidence being gathered about a period that turns out not to count.
Treat time spent in the United States as a separate question
Employment histories of this kind almost always include periods in the United States — business trips, training visits, a short assignment, a secondment — and those periods need identifying rather than averaging away. Build a travel record alongside the employment record, with dates of departure and return and the purpose of each trip, drawn from passport stamps, travel bookings and any admission records rather than recollection. The treatment of such periods depends on the applicable rules and on what the person was doing, and it is a question for counsel rather than one to resolve by assumption in either direction. What the employer can usefully do is produce an accurate account. A chronology that quietly omits three months of U.S. presence is considerably more damaging than one that shows it and explains what it was.
Write the chronology once and let everyone work from it
Employment audits go wrong when several people hold slightly different versions of the same history. Build one document, dated, showing employment periods, entities, locations, roles and travel, and record the source for each entry. Circulate that rather than answering questions individually. Where a correction is made, amend the master and reissue it. A single authoritative chronology is what allows counsel to give a view they can stand behind, and it prevents the situation in which a letter and a filing describe the same year differently because they were drafted from different notes.
