Assess the proposed continuing duties and the scope of the existing authorization before the employee begins a different role. Completion of training does not automatically authorize general work for the affiliate. Any material change should be reviewed according to the actual circumstances and case stage.
Describe the next assignment precisely
Identify whether it still calls for the knowledge originally established and what tasks the employee will perform. Obtain advice on any required step. Continued payroll and an internal request to stay are business facts, not substitutes for immigration permission.
L-1B requires qualifying related organizations and one continuous year of qualifying foreign employment during the three years before the relevant filing or admission. The proposed role must require specialized knowledge, supported by the record rather than a label. L-1B status has a five-year maximum stay limit, subject to the governing rules. Set the US assignment sequence after defining the specialized work, not merely after choosing a launch date. Capture the foreign employment proof and confidential knowledge record while the relevant supervisors and systems remain available. Recheck the assignment if the project changes from implementation of a proprietary system to general support. Continuing payroll, an internal invitation, or a booked flight does not substitute for a current basis to perform the proposed US duties. Hypothetical example: A desalination-control technician finishes a proprietary system installation, then is asked to stay for routine call-centre coverage. The employer pauses, compares the new role with the documented specialized assignment, and adjusts the plan before scheduling additional US work.
