Nepali786: My case was also received on Dec, 2018 (Texas service center). You mentioned that your are expecting the decision should be made by May, did you submit to Nebraska service center ? If it is Texas, It may take somewhere between 7.5 to 9.5 months (processing is too slow in Texas compared to Nebraska). Or it does not work this way and we can still hope that the decision can be made way earlier than 7.5 months ?
