As a baseline, all US companies are subject to the same obligations with respect to the immigration laws regardless of the owner's nationality. The law makes allowance for the need of foreign-owned companies and investors to bring non-US talent into the US who provide institutional knowledge and culture and who are most familiar with the business. Foreign firms establishing US affiliates may employ their non-US executives, managers and employees with specialized knowledge as intracompany transferees, which permits a stay of up to seven years. If the post becomes permanent, the US employer may petition forpermanent resident status for executives and managers on a streamlined basis.
If the US employer is a treaty trader/investor, it may employ persons of the same nationality in the sponsoring business, who may reside in the US for the same duration as the business principal.
