Can I purchase a house, or make some other form of passive investment in the U.S. in order to qualify for an E2 visa?
No. The E-2 regulations require that the investment that is being made into the U.S. be considered “at risk.” For example, applicable regulatory language indicates specifically that stocks and undeveloped land are passive investments and thus fail to satisfy the appropriate regulations. In determining which investments satisfy this criteria one must ask whether the investment is subject to partial or complete loss if the investment does not succeed.
