Went today and you guys were right,they didn't ask for Arabic translation but they sent me to Chamber of Commerce to have it stamped.Apparently,the one who signed my medical report was not the one they considered as official signatory.I went back to Doha Clinic and asked for that only person allowed to sign official documents, guess what? He was not there and now am waiting to have my documents back so I can re bring them again to Chamber of Commerce and Ministry of Foreign Affairs.
