What docuemnts will be required for a Type C dependant under parents sponsorship category? The dependant is 22+ years old and have always been financially dependant on parents for physical/mental condition. He has also been studying (currently in masters program) with no year gap. He has a congenital rare disease since birth which makes him dependant physically on his parents for his day to day living activities. However, he does not require any additional medications or special health care that would cost any money whatsoever. Truly appreacite your help. Thanks.
