An expatriate is someone who has left their country of origin to live in another country.
Emigrants can leave home for work and look for more profitable work in another country.
Expatriates can live abroad for some time or completely renounce the citizenship of one country in favor of another.
Retirement abroad is becoming an increasingly popular option.
The IRS may levy an expatriation tax on individuals who renounce their citizenship, usually based on the value of the property or income of the taxpayer in the United States.
