I would like to know can we receive our payments via Paypal from the countries Pakistan and Iraq. Since we are unaware of the countries where PayPal payments are available.
You can't use another countries paypal account as it would never work properly for you and would soon be limited. Paypal varies a lot country to country and can only offer the services that the banks / governments of that country allow it to offer. There are quite a few countries unable to receive paypal payments.
