My old boss in academia went through a “hire tons of Chinese chemists” phase and it got so bad he just had to eventually ban Chinese from being spoken in the lab. That seemed to work well and their English improved greatly and understanding in the lab went up. When they went back to China, hopefully they got more out of their experience here also. They learned new techniques instead of just doing things the same way they had always done them.
