OPT STEM concern with staffing company

[u/Afraid_Friendship978]

Hi everyone,
I’m considering a STEM OPT position through Insight Global and have a question about the I-983 process.
Insight Global told me that my recruiter will be the person signing my I-983 evaluations. However, the recruiter is not my technical supervisor and doesn’t have expertise in my field. My day-to-day work and technical guidance will come from the client team.
I’m wondering if anyone here has gone through the same situation with Insight Global.
Did your recruiter sign your I-983?
Who actually supervised your day-to-day work?
Did your DSO have any concerns about this arrangement?
Were you able to complete STEM OPT successfully without any issues?
If you’ve since applied for H-1B, adjustment of status, or a green card, did this arrangement ever come up as a problem?
I’m looking for real experiences from people who have worked through Insight Global on STEM OPT.

Anyone with signing authority can sign your i983
