Visitor Medical Insurance For Mother Visiting America from India

It is common for Indian mothers to visit their daughters or daughter-in-laws who are expecting a baby and living in USA. My friend who is living in the US and is expecting her first baby. Since everything about pregnancy and childbirth and newborn baby care is all new to her, she called me and said that she was bringing her mother over for six months on a US visitor visa, so she need not worry. My friends husband works in the IT industry and I know they a good life in America, but I was not sure they have the money to handle any health emergency for their visiting mother due to an unexpected sickness or unrelated injury. That is when I stumbled on a post on visitor medical insurance that did elaborate on this very topic of finding the best visitors insurance for parents visiting USA, and I did forward the link to her.
