The hospital stated he can have treatment on a tourist or medical visa does it not? They are not refusing treatment at all. It looks like they will not support DTV applications unless already a patient for a period of time. You are reading too much into one line from someone who is not a native English speaker. Bottom line. The hospital does not support DTV applications with documentation unless already a patient for this illness.
They are not refusing treatment. Did you read the post? Looks like they are saying they will not provide documentation unless the person has already been a patient.
They may want to be certain the person is genuine. There are people on the DTV happily bragging they got it for medical treatment then subsequently cancelled the appointments.
