I am Canadian citizen. I filed for family based immigration for my parents (father, mother and sister) from India. After along wait of 5 years, application was rejected due to misrepresentation. They asked for a DNA test and bummer, DNA of sister did not match. Of Couse she was adopted at birth, but all her documents since birth showed her as legitimate child. They were banned for 5 years. The sister then moved to Australia. My mother was able to get US visitor visa but father's US visitor visa had been refused 3 times. My questions: Is the ban only on father (principal applicant) or the entire family. Is this the reason why his US visitor visa keeps getting refused. Can I now apply for my mother's canadian visitor visa or wait till the ban is over? Thanks in advance.
