I've been in Portland for a month now and plan to buy a hunting rifle under the hunting license possession exception. I asked at a dealer here in Portland and they said it was fine but my question is do I need an Oregon drivers license as photo ID or can I use my passport or visa etc ? I've looked this up on a load of web pages but everyone has a different view on it so looking for the true, legal way to do this. I already bought my hunting license. Thanks for the help.
