Are your daughters presently attending a college in the U.S.? Seems they should have some advice in this regard. A cursory Google search uncovered a lot of info. I don't have any personal experience with such insurance other than a friend who does a lot of trekking in the Himalayas and obtains some sort of emergency evac coverage for those trips.

Study Abroad

Overseas Health Insurance Requirements

Towson University requires all study abroad participants to have health and accident insurance while studying abroad which provides, at a minimum, coverage for emergency medical care and treatment, hospitalization, and physician charges in the country where the Host Institution is located, as well as insurance for medical evacuation, repatriation and medical reunion.

Most US health insurance plans have some limitations for treatment outside the US and very few have medical evacuation repatriation or family reunion benefits so we strongly recommend you purchase supplemental coverage for the duration of your time abroad. You should also maintain your US insurance to ensure continuous coverage for any pre-existing conditions.
