I received notice of a successful i140 application (for eb1a) in September 2022 and have been waiting for the past 2.5 years for the dates to become current. The dates haven't moved past Feb 22 for the past 6 months or so. Any speculation on how these dates may move under the new administration?
If the current administration reduces the issuance of family based greencards (which happens mostly through the consulates), those unused greencards will flow through the EB category, allowing EB1 dates to move forward. Something like this happened during Covid.
That's a complete unknown, unfortunately, but to be clear, short of changing the green card law, there's little that an administration can do to impact the movement of the cutoff dates.
