Confused as well, we have been current for a while now not sure that bulletin means much for Nigeria. There is so much backlog and they aren't really attending to f2a i don't why i barely see anyone getting dates. The wait is very annoying.
My brother is in the f22 category . I guess this is under the f2a category which is current in the visa bulletin. Pd is Dec 2017 . We are currently waiting to get dq, does this mean once he gets dq an interview date will be available and he wouldn’t wait too long since he is current?
