Finally, I got the status. But weird that there are two entries under my name, one seems for the fee
1. We received your payment, along with one or more citizenship applications.
And the other is the application
1. We received your application for Canadian citizenship (grant of citizenship) on December 9, 2013.
2. We sent you a letter acknowledging receipt of your application(s), and a study book called Discover Canada on December 9, 2013. Please consider delays in mail delivery before contacting us.
3. We started processing your application on February 28, 2014.
Is this common?
