The worst version of this problem arrives six weeks out. The best version starts six months out. Either way, here is the shape of the fix.
The OPT hire required nothing from you, so nothing forced the follow-up conversation. Then the expiry date stops being abstract, the next H-1B window is approximately March 2027, and a person whose work you rely on is planning around a countdown.
The employee who joined on OPT has been building a record on your projects: shipped systems, publications, talks, maybe open-source presence. That record — not your petition — is what an O-1 case runs on. It files year-round through an authorized agent, decided in 15 days under premium processing.
