Austria (passport by investment)
With investments exceeding 2 million euro, the investor and his family members can expect obtaining Austrian citizenship on an expedited basis (the procedure takes from 12 to 18 months).
The aforementioned sum of 2 million euro is not legally defined, but we are not aware of any positive solutions for smaller investments.
Approval of the project (the candidacy of the investor) is carried out at the government level.
If an investor expects to receive a passport, then the investment should be considered as a donation, as there are obligations not to withdraw funds from an approved project.
