people dont read the manga.
1. genjutsu doesnt work on perfect jinchuriki because when either the tailed beast or the jin gets genjutsud the other wakes them up and snaps them out of it. that is prolly how Naruto will be immune
2. Sasky is not immune. Itachi still put his ass under tsukuyomi when he had sharingan avtive. same eye does not mean shit.
