Many insurance policies limit the amount they will pay for any single individual's medical bills or for any specific illness or injury. Major illnesses, however, can cost several times that amount. Some insurance policies limit the amount of time they will go on paying for each illness or injury. In that case, after the benefit period for a condition has expired, you must pay the full cost of continuing treatment of the illness, even if you are still insured by the company. A policy with a long benefit period provides the best coverage.
Most insurance policies exclude coverage for certain conditions.
The J regulations require that if a particular activity is a part of your Exchange Visitor program, your insurance must cover injuries resulting from your participation in that activity.

The policy must be backed by the full faith and credit of your home country government, or the company providing the insurance must meet minimum rating requirements established by the US Department of State.
