At which stage they charge your credit card

[farhaniqbal]

I sent my first application, but after a few days found some mistake in that application (i hadn't sent my wife's additional family information form). So I sent the complete application after 2-3 days of my first application. I used the same credit card details in both the applications. Now my worry is that if they charge my card for first application then my credit card limit would be over and they will not be able to charge fee for my second application. First application will be returned (not complete) and second will be rejected because they won't be able to charge processing fee

Any idea that whether they charge credit card after "completeness check" or at first they charge credit card and then check whether the application is complete or not?
