Thanks gsw

. I've called them already, however:
1. As approvals and declining process is automated, not sure how manual intervention to read my request will help as Lady at HDFC Credit card division only told me that she had noted it down.
2. Does HDFC bank in India has some mechanism where they enter into their system, details for upcoming transaction so that it goes through?
3. Do I need to give them some reference for CIC, something which will tell their systems that this is CIC, Canada charging for immigration application for which I've requested them to approve?
4. Does CIC try to charge card second or third time if transaction is declined once?
