I initially thought you were having a go, but I think you are actually serious.
Here's how DOGE can make USCIS processing "efficient". Let's say goal is to have CSC process I-129F in 90 days:
Any current applications that are waiting to be process: Reject and purge
Simple applications (no divorce, low fraud country, no criminal past, fast background check from DOJ): process normally
Slightly difficult cases (one party divorced, DOJ taking longer to get back with criminal check): Track processing, transfer to Vermont after XX days
Moderately difficult cases (foreign fiance is divorced, high fraud country): transfer to Vermont
Difficult cases: Transfer to Vermont.
Typo on application: Reject, pocket the application fee.
Missing information: Reject, pocket the application fee.
High application countries like Philippines, automatically reject 50%-75% with "missing evidence" reason. Pocket the application fee.
RFE: gone. Why waste time and resources on communications when it's simpler just to reject the application and pocket the money?
Public inquiry: Make 100% AI driven. No USCIS employee to man help lines. Any escalated inquiries send the petition to Vermont to the back of the queue
That is how to get "90 day processing" statistics on paper. Just like how Japan has a high homicide solve rate because they classify a murder as a homicide if they have already identified a suspect and have some evidence. All other cases are classified as "found body".
And, in the above scenario, your application would have been rejected twice. You would be submitting your 3rd,4th or 5th I-29F application. But hey, at lease USCIS is now processing within 90 days.
