Effective commercial rights do not themselves authorize U.S. work. Coordinate the acquisition with the applicable immigration process and actual status.
Record both sets of dates
A contract may transfer before permission is obtained, or an unresolved condition may change the proposed enterprise. Tell the reviewer what actually occurred and reassess material changes rather than treating the closing date as an immigration decision.
Buyers manage the discomfort by structuring the transaction deliberately, with the funds released to the seller or into the business rather than held in a refundable arrangement, and by doing the diligence that makes the purchase worth making regardless of immigration outcome. Set milestones in the order the evidence matures: confirm treaty nationality and ownership, document lawful funding, enter binding commercial commitments, and then assemble the application around the operating plan. Some qualifying arrangements involve funds held in an investment-in-process or escrow arrangement, so it is not accurate to assume every purchase must be fully closed before a review is useful; the actual terms should be reviewed first. Confirm the regulator's actual ownership-change procedure before signing; establish who may lawfully perform interim work before anyone travels; settle escrow terms in writing before funds move.
