The Commonwealth of Dominica offers an official and legally mandated economic citizenship to those seeking a valid second citizenship. The nationality law of Dominica authorises the government to waive the normal requirement of seven years of legal residence to acquire citizenship in exchange for an investment into their country's economy. The required contribution for a main applicant starts at US$100,000 through the Economic Diversification Fund. Alternatively, since 2014, applicants can make a US$200,000 minimum investment in pre-approved real estate from island exclusive resorts or global brands like Marriott, Kempinski or Hilton. According to officials, the citizenship by investment (CBI) programme was an economic and fiscal "lifeline" in the aftermath of Tropical Storm Erika in 2015 and Hurricane Maria in 2017, and its new investment option had become the main source of Foreign Direct Investment into Dominica by early 2016. Dominican citizens can travel without a visa, or obtain a visa upon entry, to nearly 140 countries and territories, including the United Kingdom and the Schengen Zone. Applying for Dominica citizenship requires interacting with official Government Approved Economic Citizenship Agents as the first step in the application process. This program is currently valued at 16% of the government's total revenue.
