The U.S. immigrant investor program is the most flexible of its kind in the world. The U.S. has no requirements as to age, business training and experience, or language skills. Permanent residents need not be continuously and physically present in the United States, and they can maintain business and professional relations in their country of origin because it does not require immigrant investors to manage their investment on a daily basis, but rather to ‘actively engage’ in a business enterprise, meaning they can be limited partners and pursue other professional or personal ventures.
