I know I can add him(new born baby) and passport to the application. But my problem is how to use visa card to pay his processing fee. Because visa card is the only means of paying this in my area. The fee payment form(form imm 5620) where I will put the visa card number is not clear to me as the principal applicant fee(550 CAD) has already been printed and am no more paying for this .I have paid for this at the level of the CIO. Do I rub this(550CAD) off on this form and put only the 155CAD for the baby. Hope they will not dislike this action. Can I rub it of, can i rub it off. This is my question
