Is it ok for the principal applicant to travel overseas while his application is still in process? He doesn't require a visa to enter Canada, as he holds an Australian passport. However, he's currently working on a working holiday visa, which will expire in a couple of months. He has applied for a OWP, which probably won't come through until mid 2008. If he travels after his work visa expires and the OWP doesn't come through in the meantime, will he be able to re-enter Canada?
