All Canadian, German and French skaters seem to have stayed until the end.
Among USA, Zhou was the first to come back home. Then I think Chen departed yesteday. The rest is still there.
Russian skaters seemed to stay at the training camp in Japan until few days before their competitions and then depart early after their event ended (except T/M and B/S who are doing the Gala).
Except those who are doing the GALA (M/H and C/L), Italian skaters also departed a few days after the end of their competition.
