Austria's citizenship by investment program is not for everyone.

The Austrian government can grant citizenship to foreigners who show "extraordinary merit" and contribute to the state's interests.

In Austria, applicants need to invest directly into the economy. According to Austrian law experts, setting up a business, creating jobs, or introducing new technologies can be included.

Forbes estimates the investment amount for the award to be around $9 million.

Good luck finding out who met the program's requirements, as applicants are considered official government secrets and therefore are not disclosed to any other country.
