Review each person’s actual admission and status evidence; a project schedule does not determine immigration permission.
Check individual dates
L dependents may study while maintaining status, but study does not extend a stay. Qualifying L spouses may be employment-authorized incident to status with appropriate documentation; children do not receive work permission solely through L dependent status.
Hypothetical example: a rail-signal software specialist’s child turns eighteen during a project postponement. The household should preserve the admission record, passport, relationship evidence, school plan, and current status dates; project timing alone does not determine a dependent’s permitted stay or work rules.
For L-1B, confirm the qualifying corporate relationship, one continuous qualifying year abroad in the three years before the request, and a U.S. role requiring specialized knowledge. The maximum period is generally five years, so a revised assignment must be checked against actual prior L time.
A family review should produce one line for each person: relationship, citizenship, age, current status, intended location, planned activity, supporting record, and date that needs attention. Do not let the principal’s commercial calendar answer a spouse’s work question or a child’s study question. Passports, admission records, birth or marriage records, and the actual intended activity usually settle different parts of the analysis. Plan only after those individual answers are visible.
The family should decide only after every person’s planned activity, date, and supporting record has been checked independently. A clear individual answer is more useful than a shared plan that leaves one person’s work or status question unresolved. For L-1B, compare that conclusion with the documented knowledge, actual assignment, corporate relationship, and remaining classification time before choosing the next step.
