On my "U.S. Certificate of Foreign Status of Beneficial Owner." form (doing this November 2024 from Canada) it doesn't say "U.S. Person", however it does have the "Title" field I need to fill in with something to make the "Submit" button enabled. Indeed there's no help for what's wanted in this field, and I couldn't find anything else online. Other tax things I needed to setup had me classify myself as a Sole Proprietor, so that's what I'm going to try as my "title". I have no idea!
