Start with the L-1B eligibility and application overview
Connect knowledge to the current task
L-1B can concern special knowledge of company products or interests and their international application, or advanced knowledge of processes and procedures. Unique or proprietary knowledge is not universally required. Identify the actual expertise relevant to the proposed duties. Describe the knowledge in observable terms. Identify the proprietary process, product configuration, technical history, or internal procedure; state which tasks the transferee will perform; and identify who else has comparable command. Avoid claiming that a skill is rare solely because a manager says so. A first review can compare the worker’s examples with the training usually given to new hires and with the duties of ordinary technical staff. If the U.S. job is mostly generic customer service, the connection to the claimed knowledge needs careful explanation.
Complete the organizational evidence
A qualifying relationship, a continuous qualifying foreign employment year within the relevant three years, and continuing US and foreign business remain necessary. Explain supervision and worksite. Primary work at an unaffiliated employer’s site requires review of the control and labour-for-hire restrictions. A new office needs sufficient premises and financial ability to pay and commence business; initial approval is limited to one year. The maximum period of stay in L-1B status is five years. Build the corporate and employment chronology from source records. The employee must have completed a continuous year of qualifying foreign employment within the three years before filing, and the related entities must continue doing business on both sides. Pay statements, personnel files, corporate ownership records, invoices, and operational records are more dependable than a later narrative. L-1B classification is generally limited to five years, so prior time in L status belongs in the duration decision before a proposed end date is selected.
Employment days and actual business activity
When calculating the foreign-employment year, separate time physically spent working abroad from U.S. visits; brief trips need not destroy continuity, but U.S. days do not build the required year. Confirm that the related organizations are actually doing business in the United States and another country. For this system-version assignment, use current operating records rather than incorporation dates to establish when the U.S. office began doing business. Where work occurs at a customer site, separate the customer’s project requirements from the petitioner’s continuing control. The file should name who assigns the work, evaluates the employee, provides tools or methods, and can reassign the employee. A client contract that describes deliverables can help, but it cannot replace evidence that the petitioner remains the employer and that the placement is not labour for hire. For a new office, show premises and realistic financial ability to begin operations within the initial one-year approval period.
