I came to Canada in 2012 from Pakistan on spousal sponsorship.
In Jan 2017 I am planning to sponsor my parents,brother and sister who are under 22 so assuming that they all will qualify.
But my sister has wrong DOB on her documents like ID card etc. which needs to be corrected and it is a long process in Pakistan.
Right now her age is showing up as 23 years but she is 2.5 years less than that.
Before going into process of changing her DOB I just wanted to get your opinion on have you seen any concerns from immigration officers on these kind of cases or what kind of additional documents they may ask?
