Generally, the “active” requirement is taken to mean that you have a say in the policy of the business, but is not generally interpreted as day-to-day management (though, of course, that would be acceptable). Membership of the board of directors, being a corporate officer, or the rights and duties of a member of the LLC or limited partner of a limited partnership would be acceptable. Regardless, this managerial role is understood to begin once you are accepted as a member of the new commercial enterprise, which may be upon filing or approval of the I-526 petition.
