回複：NC Cleared, 485 Pending over a year, WOM or keep waiting?

actually if your NC is cleared, it is even easier to file wom since they can no longer use 'national security' as execute for their inefficiency.

I suggest you try to do some homework before you start to file, you may actually get your case approved before you actually file wom. see more information here:
