Can I have a staff only part of a form?

I want to have client check in form so clients can check in. However, I would like there to be a portion only my staff can fill out. Please let me know how I can do this. Thank you

You can achieve this using the approval workflow features on the form.

Please check on our article guide : A General Approach on Building an Approval Process Workflow

For a simpler requirement, setting status using Conditions feature is possible also.
