The certificate attestation dept. is separate from the Ministry of Exteriors' premises. If you are heading for the airport coming from the Sheraton Hotel, turn right from the National Muzeum Roundabout and head long till you find Al-Bustan Hotel on ur right, it is in the right turn directly before the Hotel(or after it, i am not quite sure, anyway no proplem, u will find it) . in case u miss the Bustan Hotel, u may turn right from the Seef hotel . the building has a glass door, on ur left, with a paveless car park in front of it.

I hope u will easily find it.
