Hello, I'd like to Ask about if they (Case Processing Center) need my birth certificate or not, my wife is canadian and she's sponsoring me and NO children are accompaning me 'cause I don't have any, I think that they need the birth certificates of my children as confirm of my relationship to them whether they're accompanying me or not, But I don't have any Children, so do I still have to send MY Birth Certificate (I'm the Principal Applicant), or they just need my wife's birth Certificate as a proof that she's born Canadian? plz I need this info as fast as possible, Thank you very much in anticipation
