Hi aspiringtechie - Were you able to comfortably get "Separate" police certificates from both Karachi and Lahore?Not exactly sure about your case. But in my case, I have lived in Karachi, Islamabad and Dubai since I reached 18th birthday but my timelines were relatively simple:
Karachi PCC: Birth - 2010
Islamabad PCC: 2010 - 2014
Dubai PCC: 2014 - current
I think it would make sense to get your PCC like this:
Karachi PCC: 1998 - 2000
Lahore PCC: 2000 - 2004
??? PCC: 2004 - 2006
Lahore PCC: 2006 - 2008
Karachi PCC: 2008 - current
I am not sure if you can combine Lahore and Karachi PCCs such that your Lahore PCC covers 2000 - 2008 and Karachi PCC covers 1998 - 2017. My application is in progress and I am not sure what works best so take this with a grain of salt. Just trying to help. Maybe, some senior member can suggest a better way.
Thanks
