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.

Practice management, built for immigration and nothing else.
Matters, forms, documents, the client portal, e-signature, billing and trust accounting in one place. Open a matter and the forms, the family and the fee are set up. Answers given once fill every form that asks.

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.
INA § 214(n)H-1B portability to a new employer8 CFR § 214.1(l)(2)Up to 60 days, or to the end of the validity period if shorter8 CFR § 204.5(p)Compelling-circumstances EAD, in narrow cases with an approved I-140Up 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.
The 60 days are available once per validity period. Whether they were used before is not in the facts.
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.

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.
Ten EB-5 sites, one census tract at a time, took an afternoon. The script that replaced it still runs as TEA Vigil.
Bulletins, processing times and PERM queues, kept every day. That record became the Data API.
When a date will be current, whether an I-485 can be filed, whether a child ages out.
CaseVigil: every form matched to the printed page, the portal, billing and trust.
Our own model, trained by immigration lawyers to answer only from the law.
Partner at Parikh & Prasad, PC and a Certified Specialist in Immigration and Nationality Law.* Federal immigration litigation, including mandamus suits that ask a court to make USCIS decide a delayed case. Writes the software.
Founding Partner of Parikh & Prasad, PC. More than twenty years in immigration practice: EB-1, O-1, E-2, EB-5, family, adjustment, consular processing and naturalization.
