You can, and easy like others if his salry is good and if he has all other Resdidence Permit, Let him go to immigration yard outside typist sitting and waiting for him to do needfull completion of procedures. Your passport copy and photo and marriage certificate all attested sent to him first. the rest he will have to do in here. After all he is quiet new now only one month so make sure he has enough fund to entertain u in here coz doha is littile expensive now. for ex. house rent is QR. 5000/- minimum and all other will come another 7000/- too.
