i know the uae law... i am assuming that its similar here. Basically, its to ensure that your qualifications are genuine.

what i did was i got copies done (saves messing up the originals), had them stamped and signed by a Notary Public in England. Then i had to get them attested by the UAE embassy in the uk. Once in uae, they were accepted by the Labour Ministry (sometimes they will ask you to translate them into arabic)

Your best solution is to call the Qatar Embassy in London. Im sure they will know the exact process.
