i applied last month for my wife's RP. although i have a tenancy contract and i had it with me, i gave it to the counter but she returned it and asked only for Kahramaa bill (which was under my name).

as for attestations,have the "to whoever it may concern" letter and labor contract attested from ministry of labor. wife's educational certificate is not required, only you (the sponsor) as tinkerbell10 already replied.
