Hi My father is over 70 and has diabetics so can he get coverage for his stay in USA.
Your father can definitely get coverage for any new sicknesses or injuries that occur during his stay in the US. For coverage for any new sicknesses or injuries, we recommend Atlas America: http://www.visitorscoverage.com/atlas-america-insurance/
Unfortunately, there is no coverage available for pre-existing conditions for someone who is 70 years old and with a chronic pre-existing condition like diabetes. He should bring all necessary medications with him to the US to avoid paying out-of-pocket for diabetes-related expenses.
An option we have that offers some relief of diabetes-related costs is called the Careington Total Health Savings Plan that acts as a discount card: http://www.visitorscoverage.com/careington-discount-plans/
Hope this helps. Please let us know if you have any additional questions.
