Visitor health insurance, also known as visitor medical insurance, is a form of short-term travel medical insurance policy that visitors to any country purchase to obtain coverage protection for accidental injury or sickness or illness that occurs during their stay in the host country. Visitor health insurance is a form of travel medical insurance and offers health coverage for relatives or parents visiting, or for travel protection to visit any country for any reason, business or personal. This type of private health coverage for visitors is purchased as a short term health plan that provides medical coverage beyond national borders, and only for the duration of travel or stay outside home country. These visitor health insurance plans also provide medical evacuation and repatriation benefits as part of the covered features. Visitor health insurance is not currently mandatory for all foreign nationals who are temporary visitors to USA, but travelers from certain nations visiting the European Schengen states, UAE, etc. are currently required to provide proof of coverage to qualify for a visitor visa. Visitors to the United States are typically not eligible to purchase health insurance coverage like citizens and permanent residents. Only immigrants, who are not temporary visitors to USA, are eligible to purchase coverage in the new American government run healthcare exchange marketplace. Exchange visitors might become eligible for plans under PPACA after two years.
