According to the rule pdf if you have a foreign degree you will need a equivalence certificate. I have a foreign degree and applied for a equivalence certificate 2 months ago and still haven't received it.

This is what the "final approved rules pdf" says: "(1) A candidate for competitive examination must hold at least a second division or grade ―C bachelor‘s degree in any faculty of one of the Pakistani universities or an equivalent degree or comparable educational qualifications of a foreign university recognized by the Higher Education Commission (HEC), subject to production of equivalence certificate issued by HEC."

Good Luck!
