A friend of mine,,she went for interview for PR and was approved but then she asked some questions which led the officer to ask about her change of status..she married during the processing of her application and she didnt giv that information to cic immediately..the IO asked her if she wants to sponsor her husband she must do it with a new application but if she doesnt want she couldnt sponsor him "FOREVER"..
If it doesnt bother you ,,i wud ask.,,did your husband fail to check"accompany you to canada" or he failed to put your infos to his application,,does that mean he applied as single?
