I was told by the consulate in Shanghai that after having 3 single entry 90 days in a year they woukd then give me a multiple year...wo t know for sure until next visa
I just applied in Shanghai as I work there for the same Non 9 based on kids. I asked for a 1 year multiple but they said only a 90 day single could be issued. But if I applied for 3 of these, the fourth would be a 1 year multiple..
