My friend you are not clear about how a PGWP works. If you flagpole(apply at the border) then as per your circumstances you risk an instant refusal. While if you apply online the outcome would certainly be a refusal but since the processing time is more than 90 days approximately it would give you time to come up with a plan B as @scylla rightly mentioned. Heed the advice and make an informed decision as PGWP is a once in lifetime opportunity.If refused, can I reapply pgwp on border..? I know the chance to get the visa will be even lower than the first time. But I would like to explain my situation in person and ask to reconsider.. I want to do my best before moving on next back-up plan.
