If MP belongs to Conservative Party which is in Government, then he will not contact CHC-Islamabad. If MP belongs to Liberal, NDP then he might help you. I have call them few times and met him in person in Nov, 2013 and he and his his office told me that as long as processing time does not pass then will not contact CHC-Is as it can slow the processing of your and other people application because they time they spent on MP inquiries can be spent on files.
If you are not sure then perform Istikhara. Pray to Allah.

There is no written rule like that, its actually illegal - each MP differs in their response and my own MP is conservative and they did try to help us out. Party doesn't matter, it each individual MP
