That's not quite right and it's unfortunate that these USCIS goals get misunderstood so often. Firstly, they did say when they hope to achieve that goal: the end of FY 2023, so the end of September next year. Also, it's important to understand the difference between cycle times and their publicly posted processing times. USCIS has said the new goal applies to cycle times, meaning how many months’ worth of pending cases for a particular form are awaiting a decision, not how long it takes to process a form. There's plenty to be annoyed with USCIS but they've been pretty transparent about these new goals.
