Hi, After you apply for the new PR card (renewal) and then if you go abroad, can you come back with your old card even the new one is granted while you are away? (Of course, provided the old card is not expired). I do know that I can use the old card while the new one is "being processed." But my question is what if I am already abroad while the new one got granted and sent to me? (You're technically supposed to throw away the old one and use the new one.) Thanks!
