My Mother in Law, who is a Green card Holder in the US, is staying with me from Aug 9 , 2011. The Canadian Border officer clearly told us that she can stay for 6 Months maximum. The other day I called Immigration Canada call centre and the Staff says she can't stay more than 30 days !!

Can somone in the forum clarify this for me ? There are no stamps in the passport to indicate anything in this regard.

Thanks
