Many Americans enjoy traveling abroad, and while some people prefer traditional tourist destinations all over the world, others choose to visit less attractive and sometimes risky places during their vacations. Besides, some people go to places like Iran, Lebanon or Somalia as workers or for other purposes and it's impossible to forbid them visiting these places. However, when going to such risky countries you should be well aware that not all insurance companies will be willing to cover your life and you may be denied coverage if you inform them about your plans.

There are special companies that specialize in high risk travel insurance and will cover you for a higher price. However, if you have been covered previous you will still get all the benefits in case something happens to you during your travel, and you have informed the insurer about your travel plans when signing the policy.

Of course, not all countries can be classified as high risk, because there should be a combination of factors for the US State Department to list a country as a risky place for American citizens to visit. The list of such countries is updated on a regular basis and can be found at the State Department site.
