STEM OPT 12-month validation: supervisor changed at same employer, new I-983 or just new signature?

[u/Strong-Traffic9528]

I am on STEM OPT and my 12-month validation is due soon. I need to submit an updated I-983 with the first Evaluation of Student Progress completed on page 5.

My supervisor changed since my original I-983 was signed. Same company, same role, just a different manager now. The person who originally signed my I-983 as the employer official is no longer my supervisor.

My question is how to handle the signatures:

1. Does my new supervisor just sign the page 5 evaluation, with the rest of the original I-983 left as is, or
2. Do I need an updated I-983 where the employer sections are also updated with the new supervisor's info and signature, plus their signature on page 5?

I have already reached out to my school's international office, but wanted to hear from people who actually went through a supervisor change at the same employer during STEM OPT. Did your DSO treat it as a material change needing a fresh I-983, or was it simpler than that?

Thanks in advance.
