When in “Timesheets”, click on “Verify I-9”, one-by-one under the "I-9 Verification" column. This will pop-up that background actor’s submitted I-9 as well as their proof of identity documents. You will compare this with the documents they bring to set. You can either “Approve” or “Reject” this. If you reject, their I-9 will unlock in their profile so they can make edits and re-submit for you to approve. This only needs to be done once per actor, per project.
