IN THIS GUIDE · Explain work locations without treating payroll location as physical presence
Start with the L-1B eligibility and application overview
Build the chronology from real activity
Hypothetical example: payroll is unchanged during several U.S. visits. Identify actual dates, locations and work accurately. U.S. days are not foreign-employment days, and a brief trip should not automatically be treated as breaking continuity. Match travel records and project calendars to the payroll period. Where a visit involved work in the United States, describe it accurately and preserve records showing the remaining foreign employment instead of trying to classify every paid day as abroad.
Preserve the qualifying-year and capacity tests
Generally one continuous qualifying foreign year within the relevant preceding three years is required. The general foreign role may be managerial, executive or involve specialized knowledge. The proposed U.S. L-1B work must independently meet the knowledge standard. The file should identify the particular product, process, service, or organizational interest, how the employee learned it, and why the U.S. assignment calls for it. Hypothetical example: a dental-laboratory workflow specialist knows a company’s digital scanning sequence that the receiving laboratory will deploy. Training records and process materials, not seniority alone, settle the knowledge question.
Explain the actual organizational knowledge
Identify special knowledge of products, services or interests and international application, or advanced knowledge of processes and procedures. A calendar does not demonstrate that knowledge; it addresses a different part of the case. Secrecy or uniqueness is not universally required. Separate chronology evidence from knowledge evidence. The qualifying foreign employment generally includes one continuous year during the three years before filing, while the L-1B standard asks a different question about the employee’s special or advanced organizational knowledge.
Retain group and placement conditions
Show related organizations and continuing international operations. Principally unaffiliated-site work requires both principal control-and-supervision and labor-for-hire analysis, including the petitioner product or service connection requiring specialized knowledge. New-office L-1B has its own premises and financial-ability requirements. For client-site work, obtain the service agreement, scope of work, supervision terms, and evidence connecting the specialized knowledge to the petitioner’s product or service. If the customer controls ordinary daily work, the placement requires careful analysis before it is presented as an L-1B assignment.
Complete the foreign-employment and new-office assessment
L-1B generally requires one continuous qualifying year of foreign employment within the relevant preceding three-year period, along with qualifying organizations that meet the doing-business requirements. Assess actual dates and locations; U.S. days do not count toward the foreign year. For a U.S. organization doing business for less than one year, the L-1B new-office evidence includes sufficient premises and financial ability to pay the employee and begin doing business. Initial new-office approval is limited to at most one year. The L-1B maximum period of stay is five years. Decide early whether the U.S. duty, worksite arrangement, and evidence support L-1B or point to another category; a five-year limit does not convert an insufficient knowledge showing into a qualifying case.
