Expand self-verify to Canada and Mexico
Many people who work in the US commute from Canada and Mexico, they should be able to use self verify to check their employment status as well. I have found that it is possible for cross border commuters who have a US credit card with a US mailing address on it to use self verify while in the US as self verify uses Equifax. Equifax operates in Canada so it wouldn't be terribly difficult to do.
