While living abroad if you wish to authorize any individual here in Karachi you should simply adopt a procedure through which any individual can collect your Information Letter and Membership Form. Write an application along with your signature, attach copies of CNIC of both (self, to whom you are authorizing), get the application and CNICs attested through the Embassy of Pakistan and post it back to the authorized individual, who would be able to collect documents on your behalf from DHAC Visitor Building.
