For parents visiting USA, MCIS highly recommends purchase of visitor insurance to safeguard them against medical emergencies. Being insured helps in ensuring peace of mind both for the parents as well as their hosts i.e. children.
Before making the purchase of visitor insurance, there are two important questions especially when parents are the one taking the trip (or any elderly traveler):
While traveling abroad, changes in weather conditions, food and water and bug/insect bites can result in unexpected illness or stress. Even accidents, political unrest, attack and theft could lead to unforeseen medical conditions. Therefore, a traveller must always know what he needs to do deal with such medical situations. These situations may or may not require urgent medical attention and hence can be categorized as emergency and non-emergency situations respectively.
