The work experience requirement of Canadian Experience Class changed from 24 months to 12 months since Jan 1st, 2013. The application of my wife was rejected on Apr 11th, 2013 by mail. The reason was that she didn't meet the work experience requirement (she had at least 12 months experience instead of 24 months at the time the application was sent in Aug 2012). So I wonder what rule at what time does Immigrant Officer follow? Since the rule changed this year, should my wife be qualified by the time she received the letter(Apr 2013)? I don't understand how CIC works. Please comment if you know! Thanks!
