the email you got was your AORArjun3 said:I received an email from CPC-M on Monday evening..
"This confirms that your application for permanent residence in Canada has been received by Citizenship and Immigration Canada (CIC) on 2012/04/13"
I think this is the Acknowledgement of Receipt. This email included an application number, I guess this is the 'reference number' for sponsoring my wife.
I have been checking the ecas everyday now, and there is no update on it when I check it through Client ID/Receipt Number/Application Number. It's Thursday now, and I have not received sponsorship approval email yet.
Is ecase updated daily, or as the status change? Do they always send email for sponsorship approval, or maybe they send in snail mail sometimes?
and you need not worry for the approval so early. sometimes cic takes couple of weeks. even i was worried when i was not getting one. or it can be like they send you the letter (snail mail)
ecas for stage 1 is updated once a week but since you have already passed that one then my advice is keep checking ecas daily.
