It sounds perfectly reasonable, if an airline cannot train it's pilots to perform a visual approach safely then they shouldn't be flying them. Some would argue if this is the case then they shouldn't be flying at all.
I agree, I fly for an Asian carrier, and ours tries to teach visual approaches using HDG Select and VS mode while on autopilot. They even teach using the clock to time your downwind leg FFS! I'm glad I knew how to fly visuals before I came here, otherwise I might end up like Asiana 214.
The FAA already mandates this for LAHSO, so I don't see it as such a drastic step for them to take. Foreign carriers are excluded from that program as well.
Besides, American carriers rarely get fuel/time saving visuals in Asia, so why should the same courtesy be extended to Asian carriers in the US? When Air China or China Southern check into bay approach, they should be vectored out to 25 mile final, at 1500 feet, just like the Chinese do to all carriers going into Shanghai.
