Then you should ask your self a simple question why he didn't applied for citizenship by following proper procedure ? getting card through illegal ways and then expecting not get caught red handed is not possible.. Nadra have a list of everyone ,it's like a tree where branches follow the pattern and If Nadra system cant find the history of his/her father/Mother then obviously the system will put him in black list and now a days nadra is identifying the whole list of those whose identity is suspicion or system put them in different category for amny reasons, it's not a wise thing to get illegal cards and the results are in front of you and few days ago in karachi we arrested Indians they also had illegal cards and how we arrest them that thing i explained above and there are many factors involve in it which i cant tell you..
