Amazon Program Manager role Sponsorship Advice

Hi here, Got amazon program manager full time offer (resuming in 2021 with OPT- stem student). During my internship, a recruiter reached out to me that Amazon do not sponsor Program manager role, but when I asked Student Program directly, another recruiter told me not to bother about it that I can come in on OPT. I'm not sure what to do about this. I have friends who were sponsored as Program managers and Business Analyst in Amazon last year. Anyways, in worst case (if I dont get another offer) I plan to use my OPT (stem extension too) as PM at Amazon, and if they don't sponsor, I will go for masters/mba and reapply for jobs once I'm done. Any better steps or advice from Blind? L4 (new grad) Thanks
