Software for U.S. immigration practice

The operating system
for immigration practice.

One ecosystem to run an immigration law firm, built by two immigration lawyers who run their own firm on it.

NVIDIA Inception ProgramVisaVigilAI is a member of NVIDIA Inception.

What we make

Our products bring machine precision to the practice of immigration law.

One set of facts behind everything we make. The government publishes immigration data and then overwrites it. We write it all down every day, and every product reads that same record. A priority date on a CaseVigil matter is the same number the Data API serves and the free estimator shows a family at home.

VisaVigil

A model trained to reason like an immigration lawyer.

VisaVigil is our own model, trained in-house on immigration law and nothing else, not an off-the-shelf AI with our name on it. It works through a client’s facts the way a specialist does, statute first, and every answer rests on the law it cites.

Live inside CaseVigil, answering Vigil’s legal questions. A new version replaces it only after passing a blind exam it has never seen.

Regulation8 CFR § 204.5(p)Compelling-circumstances EAD, in narrow cases with an approved I-140
Answer

Up to 60 consecutive days to stay in the U.S. without H-1B employment, or until the I-94 ends if sooner. Within that time a new employer may file for you, you may change to another status, or you may leave.

What the facts don't settle

The 60 days are available once per validity period. Whether they were used before is not in the facts.

VisaVigil Data API

Ask when a priority date will be current. Get an answer, not a PDF.

The Visa Bulletin, USCIS processing times, Labor Department PERM queues and employer sponsorship records, saved every day: 6.3 million records, served to software developers in a clean, machine-readable form. Plus the calculations people actually ask for.

Built inside a practice

We file the same petitions you do.

Parikh & Prasad, PC has practiced immigration law since 2009. In 2026 we replaced the subscriptions our firm ran on with software we built ourselves, and every new case the firm opens now opens on CaseVigil. When a real case finds a defect, we fix it that week. We are the first customer, and we will always be one.

The first scriptTen addresses

Ten EB-5 sites, one census tract at a time, took an afternoon. The script that replaced it still runs as TEA Vigil.

The archiveWriting the numbers down

Bulletins, processing times and PERM queues, kept every day. That record became the Data API.

The free toolsThe questions clients ask

When a date will be current, whether an I-485 can be filed, whether a child ages out.

The platformForms that tell the truth

CaseVigil: every form matched to the printed page, the portal, billing and trust.

The modelVisaVigil

Our own model, trained by immigration lawyers to answer only from the law.

Moving your firm over

Bring your practice with you.

Switching is the hard part, so we built the move into CaseVigil. You decide what comes over, and you see the result before anything changes.

01Bring what you choose

Upload your old system’s backup. Pick the companies, contacts, cases, notes, tasks and documents you want, then see exactly what would happen before anything is brought in.

02Your matters, set up

Matter types, engagement agreements and forms ready on the first day, so the next case you open runs on CaseVigil from the start.

03Your data stays yours

Your firm has its own database and file store, and you can export everything at any time.

Security

Your clients' files stay yours.

One firm, one database

Each firm has its own database and its own file store.

Every action recorded

Who opened, changed, sent or signed what, and when, in a log built to show if any entry is ever altered.

AI is your firm's choice

By default Vigil runs on our own models and our own infrastructure. An outside AI provider works only after the firm's administrator acknowledges it in writing.

Two-factor sign-in

A password and a code from the user’s phone, with one-time backup codes stored only as hashes.

Not yet: We have not completed a SOC 2 audit, and we say so.

No sales team. Write to the founders and we will show you the platform running on a real practice.
