I-140 & Employment-Based Petitions
An unadjudicated I-140 does not sit still. It cascades into lost H-1B extensions past the sixth year, blocked AC21 portability and dependent H-4 EAD eligibility. These pages cover what breaks, in what order, and where the pressure points are.
When an I-140 stalls: what an employer can actually do
Premium processing, service requests, congressional inquiry or federal suit. The four levers available on a stuck I-140, and the order to pull them in.
Filing mandamus on a stuck I-140: timeline and cost
What the ninety days after filing look like, what the company pays, and the three ways an employment-based delay case ordinarily ends.
I-140 premium processing: when it helps and when it does not
Premium processing guarantees agency action, not approval, and the clock resets on an RFE. Where the guarantee stops being useful.
Moving an approved I-140 to a new employer
AC21 portability, the 180-day condition and the same-or-similar test. What transfers, what does not, and how a pending petition constrains an offer.
Retrogression: when the priority date moves backwards
How the Visa Bulletin works, what retrogression blocks, and why it changes the value of every downstream filing.
