Marshall Islands

The Marshall Islands is a sovereign Pacific nation in free association with the United States under the Compact of Free Association (COFA), granting Marshallese citizens the right to live and work in the US without a visa—an exceptional migration benefit rarely matched by other small-nation passports. The country uses the US dollar as its sole currency, eliminating currency risk for American-linked businesses and expatriates. It operates as an internationally recognised ship and corporate registry, making it one of the world's top flag-of-convenience states. Low-lying atolls face acute climate-change vulnerability, with sea-level rise threatening long-term habitability. Healthcare and infrastructure remain limited, and most residents rely on remittances and US federal assistance.
