I want to sponsor my parents on contributory parent visa. Can my parents include my sister's children as dependents. My sister is divorced for past 1 year and my father supports the grandchildren and my sister financially. My sister's exhusband is in middle east holding a good job but he is not helping my sister's and her kids. Both the children are minor and studying. My sister does a small job but doesnt make enough to support herself and her kids. Please advice.
