EB-1C: the multinational manager and executive green card
The EB-1C gives a green card to a manager or executive who worked for at least 1 year in the last 3 for a company abroad and is coming to work for a related US company (parent, subsidiary, branch or affiliate) in a managerial or executive role. The US company must have been doing business for at least 1 year. It follows the L-1A closely but is judged more strictly: the duties must be truly managerial or executive, and the corporate relationship must be documented in detail.
Education, not legal advice.
