Visitor insurance coverage offers medical protection for visiting parents and relatives, especially to USA and western nations. It is very important for visitors to the United States to be covered under a visitor medical insurance plan as costs of medical care are high. This is true if parents who visit USA are from countries such as India, and come to the US to meet their children and other friends for a short duration on a US visitor visa. Always visitor medical insurance for USA for their entire duration of travel outside India and stay in USA.
