485 什么时候能current啊？

140 PD 05/2018 approved 还要等多久才可以提交485

补充一下 eb1b

check USCIS visa bulletin. https://travel.state.gov/content ... -december-2018.html
Form A - PD 2016/09/01 - you can get ur 485 approved
Form B - PD 2017/10/1 - you can file 485

As for the exact waiting time, no one can give you the answer except USCIS employees.

要等很久的，最近eb2 progress 比较快，请问有没有了解过 能不能同时操作eb2和eb1？

一年到两年，多烧烧香拜拜佛，具体要多久真的没人知道。
