Assalamu Alaikum..

Hope you would be good. As you told that, your certificates have already been attested by Minstery of Foreign Affairs-Pakistan.

Further steps to be done in Qatar:
""""""""""""""""""""""""""""""""""
1st Step: So, Now you only need to get it attested by Embassy of Pakistan, Doha-Qatar.

2nd Step: After getting it attested take it to Minstery of Foreign Affairs of Qatar and get it attested from there as well.
Now no need for more attestations.

Hope it may helps you...
Wassalam
