There is no prohibition against a non-United States citizen from investing in any business in this country nor is there a requirement that such a person must declare his or her assets as a condition for doing so.For example, many non-United States citizens invest in this country's stock markets though specific stocks (Nasdaq, New York Exchange and American) who are residing in Europe or other countries and they have no obligation to declare their assets before doing so.What this foreign investor will most likely have to declare is the amount invested in your business and any returns received for state and federal income tax purposes and actually pay the monies owed before the distribution can be taken out of this country.Good luck.
