CIC will try to debit your credit card but when transaction will not approved they will send you a mail asking you to re-submit the form in 30 days and attach that letter with your form. You cant change it now you will have to wait for response from CIC . Normally applicants resend the full application before they receive any response from CIC which i think is not a good practice.
Wow.. then if I re-submit the credit card information when I receive their email, how my application will be assessed? Will they assess my application using the conditions after 4/10, which means the English ability (exam) must reach certain level to apply for the visa. Because they received my application on April 9, 2010, if they use new conditions for my application, it will be a huge disadvantage for me.
Same thing happened to me i lost my card. My application was received on14th may, as u have sent ur app. before me u will receive response from cio earlier than me. pls share the progress of ur case it will really help. I m also waiting for their response.Thanks.
