The U.S. Citizenship & Immigration Service (USCIS) and the U.S. Dept. of State, generally, will not approve speculative investments where one merely invests X amount of dollars and waits Y amount of time in order to profit from the appreciation of its value. They want to see your enterprise grow in personnel size and revenue, which requires more than an investment in a plot of land or a house. Your business must offer a service or product.
So, if you have sufficient real estate assets and have a desire to move to the U.S., you need to register your first company (if you don’t already have one), transfer titles of your real estate assets to this company, and then have that company offer a service related to real estate. Because of the application’s flexible requirements when it comes to employment with new startups, you only need to hire one person to manage your properties and offer property management services to other property owners in the area. Give this property manager the tools (computer, website, marketing, office) to do their job, and you are one step closer to having your commercial enterprise with real estate assets. And if by chance you prefer to keep the properties in your personal name, you can also have your enterprise manage your own properties as its own client.
