Do not treat a share purchase as a substitute for the actual L requirements. Have the role and company relationship assessed before assuming ownership would resolve any issue.
Keep investment decisions separate from eligibility evidence
Clarify professional preparation and current official charges. A purchase may involve separate business and legal considerations, but the expense does not establish qualifying managerial or executive duties. Hypothetical example: an airborne survey company suggests the transferring manager buy into the U.S.
affiliate to strengthen the case, at a price the household would have to borrow. Treat that as two decisions. The immigration question is whether the role and the company relationship are demonstrable as they stand, and it should be answered first, because money spent to fix a weakness that does not exist is money spent for nothing.
Ask counsel to identify the actual gaps and what evidence would close them; the answer is usually documents and employer cooperation rather than capital. Budget separately for professional preparation, translation of foreign entity records, and current official charges confirmed at the time of filing rather than taken from an old quotation. Where a purchase is wanted for business reasons anyway, record it as a business decision with its own tax and corporate advice and keep it out of the eligibility narrative.
A purchase also carries consequences if the transfer does not proceed, which is a further reason to sequence the two decisions instead of combining them.
