Employer signature
The I-983 does not necessarily need to be signed by your direct supervisor. The person who signs on behalf of your employer must be an employee of the company, have the authority to sign to the terms outlined in section four and be familiar with your training plan as outlined in section five.
Any time revisions are made to the I-983, the signatures in sections two, four and six need to be updated with new signature dates. This shows that all parties signing the I-983 agree to the changes.
Notice that the document must be signed by all parties, including the student. Electronic signatures are permitted
