thanks for the reply.Even if approved getting supervisa insurance may be difficult and expensive and anything nephrology related may be classified as preexisting condition. Is your father being followed by a nephrologist? Is he diabetic? Supervisa is meant to visit Canada and supervisa insurance is only emergency medical coverage. If you have chronic health issues a long visit to Canada may not be possible.
He has no diabetic .I already have insurance that i bought and attached to the application .
