Do not treat that as established without supporting facts. Customer conversion and contract transfer are commercial events separate from the immigration process.
Plan for the actual opening conditions
Identify which contracts are effective, which customers remain prospective and what resources are ready. Keep forecast dates clearly labelled. A purchase payment does not guarantee business activity or authorize the investor’s U.S. work. Coordinate the proposed opening with confirmed rights and applicable status or admission steps.
Hypothetical example: a language-services entrepreneur wants to buy a translation agency, but the seller will release the client database only after closing and two contractors have not agreed to continue. Use a closing checklist that separates completed commitments from unresolved dependencies. The applicant must show treaty nationality, substantial capital exposed to loss, a real non-marginal operation, and personal direction and control; an opening date on a brochure cannot prove those facts. Start with the source of funds and transaction conditions, then document premises, assets, staff, agreements, and the first operating steps. If escrow conditions make funds returnable, explain them precisely and assess whether the commitment is sufficient at the intended filing date. Do not begin U.S.-performed work simply because the business has been purchased; admission or status must support the activity. A prudent calendar leaves time for client consents, licences, and evidence collection rather than recasting pending items as finished after a filing is made.
