Need to follow directions
In the letter from CIC it clearly indicates to mention the expiry date of your CIC request letter. If one writes that date on top of the FBI finger print envelope, they will take care. The normal process time for FBI is 6 to 8 weeks per their web site.
If anyone experience more than that time line, there is process to expedite that too. Please use their web site and numbers to reach them and have them send FBI cards soon.
Please follow the Site, forums and judge the information, rather mouth of word from here and there. That saves lot of time and keep you worry free.
Wish you all the best
