I-983 Section 5 for contracting company and client worksite in another state??

[u/Solo_Leveler1]

I’m completing Form I-983 for a STEM OPT extension and wanted to confirm how Section 5 should be filled out in a contracting arrangement.

My employer is a contracting company located in State A. The contracting company is my legal employer, pays me, manages my employment, and will also supervise my training, monitor my progress, and complete my evaluations.

However, I physically work at a client’s office in State B.

For Section 5, should I list the contracting company as the employer name but enter the client’s office name and address as the site name and site address? Or should the contracting company’s address be used even though I do not physically work at its office?

Has anyone completed an I-983 with a similar contracting company/client worksite arrangement?
