we can't compare one application with another application. But, Whole process will be completed with in the time frame of 16-18 monthsBut their process is kinda weird
They are sending MR to May, June and July 2017 applicants when april applicant are still waiting. If they send out in batches then one batch was send on 14th march and the other on 19th march and the recent one on 22nd march
Lets hope for the best.
