Global Health Insurance plans are designed for expatriates – individuals, families or groups who are currently living outside of their home country or country of citizenship.
If you are residing in your home country, then it is not usually possible for you to purchase a Global Health Insurance policy.
This means that an American national living in the USA, a British national living in the United Kingdom, or a Nigerian national living in Nigeria would not be able to purchase a Global Health Insurance policy and would need to look at locally available health insurance options.
The exception to this rule is for Hong Kong nationals living in Hong Kong.
