U.S. Citizenship and Immigration Services has issued a final regulation governing the use of parole on a case-by-case basis with respect to entrepreneurs of start-up entities who can demonstrate through evidence of substantial and demonstrated potential for rapid business growth and job creation that they would provide a significant public benefit to the United States. Such potential would be indicated by, among other things, the receipt of significant capital investment from U.S. investors with established records of successful investments, or obtaining significant awards or grants from certain Federal, State or local government entities. If granted, parole would provide a temporary initial stay of up to 30 months (which may be extended by up to an additional 30 months) to facilitate the applicant's ability to oversee and grow his or her start-up entity in the United States.
