Ok, maybe you should reply to the appropriate post to make it easier to understand
Did you do your undergrad from LUMS? If so, then well done fellow Luminite.
You don't need to provide PCC for Lahore. I can't remember what personal history asked but I think the only PCCs you are asked to provide are for the ones in your address history.
I basically put just one single address in my address history because that was PERMANENT address which happened to be in Karachi. It didn't matter that during that time I was not living there. I was attending LUMS in Lahore but my permanent address was in Karachi. I also recall that the police officer told my dad that if an FIR is filed against someone, it shows up at the permanant address of the individual. The permanent address is listed on the ID card. It doesn't matter how many temporary addresses you change during your period of PCC. As long as you cover your permanent address, you are fine.
I also guided people with the same process. Every one of them turned out fine.
Is that clear?
