No. L-1A generally has a seven-year maximum, and prior time in H or L classifications can count toward the limit, including time with other employers. A new petition does not automatically reset the clock.
Reconstruct the full history
Gather approval notices and admission and travel records for counsel to calculate available time. Specific rules can apply to time abroad and certain intermittent or commuter arrangements, but they require facts and evidence. If moving from L-1B to management, additional rules govern eligibility for the longer total period.
Avoid committing to an assignment length before that review is complete. Suppose the history you relied on turns out to be incomplete after the assignment length has already been discussed internally. Hypothetical example: a surveying-instrument distributor calculates a transferee’s available time from company records, then a passport reveals two short L-1B admissions for a former employer that nobody had listed.
The requested period has to be recalculated, and the promise made to the business has to be corrected before it hardens into a staffing plan. Handle this by re-running the calculation whenever a new record appears, telling the sponsoring manager the same day, and reissuing the assignment letter with the revised end date. Prior time spent in the United States in H or L status counts toward the seven-year L-1A maximum whether or not the earlier employer was related to the present one.
