Sequence it around evidence rather than a preferred opening month. The file is strongest once the commitments behind the turnaround exist and the capital is irrevocably devoted. Prelaunch or pre-takeover readiness can qualify with credible commitments, and first sales are not universally required before a filing is prepared.
Set milestones that can move without breaking the plan
Fix dates for due diligence, the funding trail, signed lease and supplier terms, and the reviewer's assessment of non-marginality. Place the filing after those, leaving room for follow-up questions. Remember that visa validity and the authorized stay recorded on the Form I-94 are different periods. Because E-2 is a nonimmigrant category, keep the intention to depart when status ends consistent with the household's other commitments.
Set milestones: resolve the cap table, sign or amend the agreements, complete the funds trail, and have the whole package reviewed. When issuance of the visa is the only condition left on their release, official guidance treats them as irrevocably committed. Useful milestones: the seller's substantiation package received, an independent valuation reviewed, the source and path file complete, contract conditions settled with counsel, the application prepared. Consular scheduling varies, so a buyer aiming at a May opening should be applying in the winter.
