[Q] Can I invest $1 MM to buy a building or house and qualify for an EB-5 case?
No, for two reasons. First, just buying a real estate and holding it is not considered to be a commercial activity. Second, how are you going to create 10 new, full-time positions through such investment?
However, if you purchased a shopping center or a golf course and added 10 new, full-time jobs within 2 years, then, yes, no problem.
