The EB-5 Immigrant Investor Program is the most flexible in the world. It sets no requirements for age, business training and experience, or language skills. Additionally, Permanent Residents need not be continuously and physically present in the U.S. for at least half the year during the program. They can even maintain business and professional relations in their country of origin, as long as it is not under U.S. sanctions. Generally, as a permanent resident, the investor and his or her family are free to return to their homeland for visits or business purposes, as long as they do not intend to abandon their residence in the U.S.
