Begin only when the applicable authorization and admission or approval steps permit the proposed U.S. employment. Company urgency does not substitute for status.
Plan around evidence dates and business readiness
Work backward from the desired U.S. start date. Confirm whether the foreign employment record contains twelve uninterrupted qualifying months within the relevant lookback window and whether any travel or employment change interrupts the story.
Then map the corporate documents, role descriptions, and, for a new office, premises and operating records needed for the intended filing. A company may have a launch announcement, a customer deadline, or a board meeting before the principal can lawfully perform the U.S. job.
Those dates are business facts, not permission. The organization should decide who can cover early operational tasks and who may sign or manage matters until the proper start. After approval, entry documentation and the period of authorized stay deserve the same attention as the petition; an approval notice is not a substitute for checking the admission record.
For a new office, record the first-year milestones well before the expiration point, because extensions examine whether the operation now supports the claimed senior role. A realistic timeline is more useful than an optimistic one built around a single expected date. Record substantial company changes as they occur, including ownership shifts, closure of an overseas unit, or a major alteration to the proposed role.
The relevant organization must continue to qualify. An early factual update is preferable to discovering at an extension or admission stage that an old petition narrative no longer describes the business.
