I have sort of a similar timeline. They received mine on January 28 at the Nebraska service center. They were a bit late with my biometrics letter. I had to call USCIS in order for them to finally send the biometrics letter. My appointment was on April 14th and it's still on initial review. I really hope I don't turn to those one year plus cases like I have been reading about on here. I want to get approved by the end of this month or even next month. It's all wishful thinking. *sigh*. Good luck everyone.
