Worldwide Health Insurance is also known as expatriate health insurance. It provides long-term health coverage for those who are living and/or working abroad for long periods of time. These plans are designed to provide access to the best possible healthcare, wherever you are in the world.
For example, let's say you're an American citizen who spends 6 months of the year living in Mexico. Having global travel medical insurance would give you flexible medical coverage while you're enjoying your extended stay in Mexico.
