I would like to bring my sister who lives in Iraq to Canada for a visitor visa. Me and my husband can financially support her and she will be living with us. She is 48 years old and not married with no kids. She works as an engineer in Iraq. We have tried many times to bring her to Canada but our application has always been refused. We would like to know if there is something we can do or somewhere we can go to make a visitor visa for her. Thank you
