Downgrading can shave months off if EB‑3 dates are ahead, but you’ll likely face longer I‑140 processing and pay duplicate fees.

Do it only if you’re current in EB‑3; otherwise you risk two queues, extra attorney work, and possible RFEs on job level.

 Keep EB‑2 and file a concurrent EB‑3 I‑140 (“inter‑filing”); you gain flexibility without abandoning the original priority date.
