Ali Bin Ali is authorized reseller and repair center here in Doha. I bought my iMac from them and asked them if they honor apple care purchased from another country. they said yes and it is not a problem as long as the warranty or apple care is still valid.

their repair center is in Mansoura. sorry but i do not know the exact address.

you could ask ispot in city center 44115204 and w hotel 44122591 because they are the apple store of Ali Bin Ali.
