Citizenship by Investment (CBI) is the process of acquiring fast-track citizenship and passport by making investments. These investments can be in the form of donations or in real estate usually starting from $100,000. Family members also receive the citizenship perk. Although the CBI schemes have existed since the 1980s, their popularity picked up only after 2010, due to the rapid rise of globalization, tourism, and more people wanting freedom of movement without visas.
