Should I get character certificate from Police? What should be the procedure
Visit your area Police Station with your Passport and NIC than they will ask you to fill the form plus bribe as well
(IF YOU DON'T HAVE ANY SOURCE THAN BE PREPARED TO BARGAIN WITH THEM) they will take some hours to complete the process than, you have to go Zone Head Quarter for further process they will again ask you for bribe to process your case and after a day you will get your Certificate.
NOTE: PROCESS in KARACHI is like this, don't know about other city.
