We have movement for F2B for April Bulletin.
Final Action Date moved to: May 22, 2017
Filing Action Date moved to: August 8th, 2017
I am finally current! Hopefully good news for others as well!
July Bulletin is out with more movement. F2B final action date is Oct. 15 2016 (so slightly less than a month forward). No change to filing action date.
Yes, it is definitely hard to tell what is going on. Different embassies prioritize different things, and then there's the randomness/luck aspect as well. That's an interesting real-life example.
By the way, what is the 60 day email you reference?
Yes, for some it may make sense to switch categories. You may be able to file sooner if you do switch to F1, but if you will get approved sooner is the unanswerable question.
Finally, some more movement and that's awesome you are now current! Definitely keep us update and hopefully you have your interview soon.
I wonder why they haven't moved the filing action date yet. There's only ~ 5 1/2 months between filing date and final action date now.
