In all, it took 11 months for GC approval since filling with some months of silence (6 months in total which is normal). I don’t know if my use of EMMA prompted new activity on my case on May 27, but I will advise you use it wisely. Yes, the US immigration system is unfair and expensive to those willing to abide/respect its rules. But, take it from someone who has been in this country for almost 13 years; trust the process, it somehow works!
