Assalam-o-Alaikum all!

I want to reappear in 2010 but there are couple of questions that are bothering me in that regard:-

Do we need any permission for submitting our applications as other government servants do?

Should I choose my home-station (Rawalpindi in my case) or Lahore as the centre for exams?

I would like some advice on these from fellow members.

Regards,
Ahsan.
