No. Payment or petition progress does not itself confer present residence or work authorization.
Plan staffing around individual official milestones
Nothing on a company calendar creates permission to work. The sequence that matters runs one person at a time: the underlying EB-1 or EB-2 classification has to be established for that individual, the published Gold Card steps and payment completed as the official instructions require, admissibility resolved, and a visa number available for that person's classification and country of chargeability. Only the final event, admission on an immigrant visa or approval of an adjustment of status, permits U.S.
residence or employment. A cleared payment, a filed petition and a scheduled interview are all progress, and none of them is authorization. Two employees who start together will not finish together, because different classifications, different chargeability, different vetting outcomes and different civil-document delays pull the dates apart, so a shared launch date is a business hope rather than a plan.
Build the staffing schedule around the latest realistic date rather than the earliest, and keep a fallback for the role if one case runs long. The payment itself starts no clock: it is a nonrefundable contribution from the applicant to the U.S. government with a separate processing fee, not a visa in itself and not an EB-5 investment, so it advances a step in the process without moving anyone's status forward by a day.
Since the published terms and processing steps are still settling, re-check the official program page before relying on any stated timescale. A U.S.-licensed immigration lawyer can say which dates in this sequence are actually within your control.
