dear nagz, let me tell you something, its weird how this happened twice in 1 day , a friend of mine got the exact same email, and he ended up going to the embassy and they interviewed him and he was told the only reason they asked is if you have an investment/career/assets in another country why should canada trust you wanting to move your location, its a stability question..... if its a stable job/business, they question it since they want to make sure that the person has NO OTHER options than canada, but for example if i have 5 business' in 5 countries and my wife SPONSORS ME they would wait, why does he need sponsorship, why doesnt he just invest?! they want to boost the economy of canada so basically they are saying if you have money already why are you being sponsored, just buy a land in canada and you will be a citizen, so as long as your husband can prove that this isnt a life invest or anything the case is fine , dont worry about it , and regarding mail, its just a timeline, they gave my friend the same time limit, but he couldnt meet it, since he only had 12 days and mail took 15 days, but he provided the info and it was fine
