I'm an American in Canada and overstayed my visitor limit by 4 months, going on 5..if my gf sponsors me outland for common law, and then I apply for an extension so that I can travel back and forth more reliably..what are the chances they will grant me an extension at this point? I know it's seperate from the common law, so I'm thinking they may not grant the extension since I already overstayed by 4 months. Thanks in advance for all your help.
