It started with ten addresses.
Our firm needed to know whether ten EB-5 project sites qualified as targeted employment areas, the answer that decides whether an investor puts in $800,000 or $1,050,000. Nothing would simply answer it, so we checked one census tract at a time, and ten addresses took an afternoon. Somewhere in the middle of the list it became obvious this was a script. That script still runs as TEA Vigil, and it takes a whole list of addresses at once.
Writing the numbers down
The Visa Bulletin is public, but it is spread across 130 separate pages. USCIS processing times change without notice and keep no history, and the Labor Department’s PERM reports were scattered enough that we rebuilt years of them from web archives. You can research a question later; you cannot research a number nobody wrote down. So we started keeping all of it, every day. That record became the VisaVigil Data API.
Answering the questions clients ask
With the history in hand, the questions we heard every week became calculations: when will my priority date be current, can I file my I-485 this month, will my child age out at 21. The Priority Date Estimator, the I-485 Filing Check and the CSPA Age Calculator came out of them, free for anyone.
Rebuilding the practice
Our firm still ran on two subscriptions that did not talk to each other. In 2026 we built the platform we wanted instead: CaseVigil. Matters that set up their own forms, family and fee; a client portal that collects answers by section and signatures in order; billing that keeps filing fees apart in trust; a PERM desk and USCIS case status. The forms taught us most. The first one we took apart had a box named for an email that was really a phone number, so every form was matched to the printed page, box by box, before it was allowed to file anything.
Building our own model
We built a library of primary law, re-read on a schedule: the statute, the regulations, the manuals and the decisions. Then we built VisaVigil, our own model, trained by immigration lawyers on the firm’s own questions to answer only from that library and cite every source. It is not an off-the-shelf AI with our name on it. Inside CaseVigil, Vigil uses it to answer legal questions, citing the provision and the date it was read.
Each tool solved a problem on a real case. Together, they became the platform.
Every new case our firm opens now opens on CaseVigil. When a real case finds a defect, we fix it that week. We are its first customer, and we always will be.
