From Malta to Austria, these are the 11 countries where you buy citizenship, also known as a 'golden passport'

Even if you can afford the multi-million dollar price tag, Austria's citizenship by investment program is incredibly selective.

Under Article 10, Section 6 of the Austrian Citizenship Act, the Austrian government is able to award citizenship to foreigners who show "extraordinary merit" and contribute significantly to the state's interests — either scientifically, culturally, or economically.

Unlike in other country's, applicants must invest directly into the Austrian economy. This can include setting up a business, creating jobs, or introducing new technologies, according to Austrian law experts.

The exact investment amount required for the award is not clear, but is estimated to be around $9.5 million, Forbes reports.

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

There are four ways to qualify for Antigua and Barbuda's citizenship by investment program.

Applicants also can invest in "designated, officially approved real estate" worth at least $400,000, which comes with a $30,000 processing fee.

The program's final and most expensive option is to invest at least $1.5 million into an approved business on the island, along with a $30,000 fee.

Alternatively, applicants can invest in an approved real estate project with a value of at least $200,000.

St. Lucia, a volcanic island located in the eastern Caribbean Sea, offers four different investment options in exchange for citizenship.

The least expensive option is a $100,000 donation to the island's National Economic Fund. Applicants who prefer to invest in real estate can purchase property worth at least $300,000, which cannot be sold for five years.

Additionally, you can invest a minimum of $3.5 million in an "approved enterprise project," which range from restaurants and cruise ports to universities and transportation infrastructure. The projects must create at least three permanent jobs in the local economy.

The final option is to invest a minimum of $500,000 in government bonds, which is currently discounted 50% under the COVID-19 relief program.

Jordan, a semi-arid country bordering Israel, offers three investor-citizenship options, according to Henley & Partners.

Malta, an island nation off the coast of Italy and member of the European Union, was the subject of an investigation regarding "loopholes" in its citizenship by investment application.

Now, the program has one of the "world's strictest due diligence standards and vetting of applicants," according to Henley & Partners, which was involved in the scandal. However, the EU is still considering a ban on golden passports offered by member states.
