As i wrote earlier u need to get attested it from Education Board, Ministry of Foreign Affairs in Islamabad or its camp offices in Lahore, Karachi, Quetta and Peshawar, and lastly if u would like to use it in KSA or any other country (as per your destination place) than u may attest it from KSA embassy/consulate in Pakistan. If some reason, it is not possible for u to visit KSA embassy/consulate in Pakistan than after arriving in KSA, get attested from Paksitan Embassy/consulate in KSA and than Ministry of Foreign Affairs of KSA.
For More Details, Please read this carefully:
The applicant himself or his blood relatives can submit the documents in the Consular Section. The person presenting the documents on behalf of his relative is required to show his/her original ID card/Passport/Driving License/University Card/School Card/Domicile/Office Card or any of his valid ID. If no blood relative of the applicant is residing in Pakistan , the applicant is required to give an authority letter duly signed by our Mission abroad to the authorized person to be brought at the counter alongwith his documents.
The documents needing attestations can be submitted at consular office window from 8:30 a.m. to 2:30 p.m. during the working days i.e. Monday-Saturday except Friday. Official timing for Friday is 8:30 a.m. to 11:30 a.m. The attested documents are returned to the applicants after two hours of submission of documents.
Note: if u paid more than amount described above and attestation is done through the agent than believe me there r more chances of appearance of atttestation (seal and signature) fake. If any competent authority verified it and found fake, a legal action will be takan againt the degree holder of caused seized of his degree.
So my sincere advised is that u may go by yourself in the said office and get it attested.
