I traveled out of Brazil shortly after I picked up my CIE card from Policia Federal. While leaving I gave my passport and CIE card to the lady at the Counter in the Airport and all she did was to stamp me out without indicating how long I was permitted to be away for (That's the stipulated 2 years). I was just wondering if this invalidates my CIE card and permanent visa because there was nothing really different from my earlier exits from Brazil on tourist visa.
