Being a sole shareholder does not disqualify a transfer, but the U.S. role still needs to be shown as primarily managerial or executive in actual substance, not simply as an extension of ownership authority.
Document the managerial functions specifically
List the specific supervisory, policy-setting, or organizational-management duties the role will perform, and distinguish them from the applicant's general authority as owner.
Separate ownership from the immigration tests. Prove a qualifying parent, branch, subsidiary, or affiliate relationship, plus one continuous year of full-time employment physically abroad within the relevant preceding three-year period. L-1A requires a primarily managerial or executive U.S. position; share control cannot establish that capacity. Organizational business must continue in the United States and another country throughout the stay. An initial new office need not operate yet, but it requires secured physical premises and evidence addressing the U.S. investment and the foreign entity's financial ability, together with a first-year plan showing that the operation will support managerial or executive work within one year. The qualifying foreign year must itself be managerial or executive. A common error is substituting ownership title for duty evidence.
Hypothetical example: The sole director of a Tecumseh tool-and-die firm forms a U.S. subsidiary and proposes personally quoting jobs, programming machines, inspecting pieces, and supervising future hires. The file identifies which operational tasks will move to technicians, when delegation occurs, and what personnel or essential function the owner will manage. Payroll and duty records establish foreign employment separately from the share ledger. If production work occupies most days, sole ownership cannot convert that schedule into an L-1A role.
