Is your, presumably Afghan, licence an ICAO one?
Most countries will permit you to fly with PPL privileges on a foreign ICAO licence. The mechanisms vary from country to country, inevitably - from the UK where you just get on with it, to the USA where you need to have security checks and your licence formally validated.
It seems to me that your best bet might be to see if you can find a friendly flying club somewhere in Pakistan?
This might help?, who can help you sort out whatever validation is needed in Pakistan and the ability to rent and do some local flying, with or without a local instructor.
