Initial new-office approval is limited to at most one year; an extension requires its own evidence and decision.
Prepare to show actual development
Retain operating, staffing and role records. A forecast or initial approval does not automatically establish that extension requirements will be met. Create separate timelines for overseas employment, U.S.
entity development, staffing, and any prior L time. The first review should determine whether the foreign qualifying year fits inside the relevant 36-month lookback and whether the U.S. role will be supported by the proposed start.
Hypothetical example: a specialty-glass importer wants to transfer its operations chief after eleven months abroad, with a two-week U.S. training trip in the middle. The parties should document dates and capacity carefully rather than assume any absence has no effect.
New-office initial validity is limited, and later extension review examines actual operations rather than the original forecast. L-1A time is subject to a seven-year maximum, so previous L classification use should be counted before setting a multiyear leadership plan. Do not promise a customer that the transferee will be available before the required permission is obtained.
The practical sequence is to confirm qualifying history, assemble present business records, identify the correct filing date, and preserve operating evidence for later stages. If staffing or premises change before submission, update the role description and supporting chart. A realistic amended schedule is more useful than retaining an obsolete launch assumption in the supporting record.
