I wouldn't advise you doing that, they may cancel your Oath, just travel and go back to do your Oath.Hello everyone, I was waiting for my oath invitation. My pr card already expired and applied for renewal for urgent process but it didn’t approved yet so I travelled and will go back on PRTD . So do I need to let the citizenship department know about my travel ? Or not so they can update ?
Another point, If your travel is less than one month don't take the risk because getting PRTD may take up to 6 weeks..... Consider getting back to Canada through land border in case you don't get your PRTD however you need to have an US visa or your Passport is already allowing entering to USA
