My wife mailed mine on Dec 4, 2017. My mistake....not telling her to send it registered mail. I am not even recognized by their website to check status yet. Also am not sure about the place of birth question as to exact syntax they will use in regards to commas, fwd slash, town and district I was born in. So I phoned today, Jan 9, 2018, and the lady said it might be in the building but can't tell me that. So unfortunately for me I won't know if it got lost in the Christmas mail surge.
Update: just showed up online Jan 19. It states: Application Received on 2017-12-11
