Medical insurance plans for new immigrants are entirely different from permanent residents. New immigrants and green card holders are not eligible for the local medical plan, and they have to buy travel medical insurance that will provide adequate coverage.
Therefore, if you are a new U.S. immigrant and visiting it for the first time, or a green card holder but living outside of the U.S., visiting the U.S. only for a short span, must go with travel medical insurance that will provide you temporary coverage to stay protected.
