Arien..I knew abt. one guy who has got Family visa, without attestation and even without a Salary transfer to the bank. May be he is very lucky

And for attestation I got all my certificates attested from India, the procedure is :-
1. Get attestation from Ministry of HRD
2. Get attestation from Ministry of External Affairs (Foreign Affairs)
3. From respective Embassy..(in this case Qatar Embasy if you are attesting it from India)

The thing is that without the (1) you will not get (2) and without (2) you will not get (3)
