就是140的filing date，
不知priority date 有啥意义？
485的快慢是否取决于其RD，跟priority date有关吗?

It is used to decide which 485 to process when EB1 not current. 485 with a
priority data may be processed only when it is early than the cutoff data or
when the cutoff data is current.
Now EB1 is current, so no use at all: all 485 can be processed.
