I have to take a trip from Europe to USA. Is it true that if you have no medical insurance you cannot be recovered in a hospital ? If you fall on the street with a heart attack that won't bring you to the hospital unless you are insured or pay? I think people who told me this are exaggerating. Exactly how does it work in the US if you need medical/hospital assistance ? Is it true you must pay very large sums of money if you are unfortunate and get sick there ? Thanks for letting me know really how it is!
