If you need to make an update to your I-9, here's how to do it:
Navigate to your I-9 Page by clicking on Myself>Documents & Forms>I-9 tab
Here you will be able to see what is currently stored in the system for you: both S1 that you filled out originally and S2, which your manager or HR contact would have completed.
If you'd like to update the information listed on the I-9 that you originally input, you'll want to look a little further to the right and click on the highlighted "S1" link under "Actions."
Once you've input all the information needed, you can scroll down the page and hit "Submit."
