Hi Sehrawat,Chintan, your observations are absolutely correct. In the downloaded IMM5406 it is clearly written in the address column header ' in case of deceased city, country and date of death to be given'. Whereas such instructions were missing in the online form and as result, a number of members are reporting returned applications. After resubmission of completed IMM5406 it takes two months restore the status to 'submitted'. Other members may however share their views.
IRCC has provided that question in online form actually. It is right above the address field. We missed to notice that question during online submission.
