Negotiation and evidence usually take months; the application is the last stage. Escrow tied to the decision lets the deal wait for the outcome instead of forcing a choice.
Let the transaction structure absorb the wait
Work backwards from the seller's willingness to wait. Due diligence on three years of records, agreement on what is being bought, drafting a purchase agreement conditioned on the immigration decision and setting up escrow will typically take longer than either party expects, and the source-of-funds file often needs documents from a bank or an accountant that arrive slowly. Only then is the application ready to be made. Processing times at consular posts vary and are published; check the current position rather than relying on a figure from someone else's case. The structure that protects both sides is a conditional agreement with money held in escrow, so that a refusal returns the funds and an approval closes the sale. A seller who insists on completing first is asking the buyer to carry the whole risk.
Hypothetical example: an ice-rink refrigeration service buyer wants to close before the winter maintenance season, but the seller's tax records and equipment titles are incomplete. The first review should establish a sequence for diligence, agreement terms, payment commitments, entity formation, visa submission, and operational launch. Title records and financial statements settle what is being bought; the contract controls when risk attaches. Do not let the seasonal calendar replace diligence. A frequent mistake is committing money to meet an opening date before confirming that the business and its records can support the application.
