Welcome to the forum my friend,
This game needs alot of paitience. Now that CHC-Islamabad has received your file, now they will send an AOR (Acknowledge of Receipt) along with supp form. After that don't expect anything from them atleast until the next 10 months thats when your file will open next. After that, they will go through the initial process and see if they need anything else from you. If they do, you will be contacted and if they don't then you will hear something within 16 months if your case is straight forward. You will either get a Passport request, rejection letter or interview call. During this whole process they do send some form in the middle of the process to get your updated information. These day, female cases are taking anywhere from 14 - 18 months and male cases are anywhere from 18 - 24 months. So sit back and relax for a while you have a long wait my friend. Applicants from 2009 are still waiting for their process to finish still. Hope everything goes well for you guys.
Below are some general steps they go through just to give you an idea...
