# VisaVigilAI

> VisaVigilAI, Inc. makes software for U.S. immigration practice. It was founded by two immigration lawyers, Rajesh Prasad and Bindi Parikh, who run their own firm, Parikh & Prasad, PC, on it. Its products include CaseVigil, VisaVigil and the VisaVigil Data API. VisaVigilAI is a software company, not a law firm. Nothing it publishes is legal advice.

## Products

- [CaseVigil](https://visavigilai.com/casevigil/): practice management built for immigration and nothing else. Its own site is https://casevigil.com.
  - Matters and USCIS, State Department and Labor forms, each matched box by box to the government's printed page.
  - The client portal, with questionnaires by section and e-signature.
  - Billing, and IOLTA trust accounting that keeps filing fees apart.
  - Vigil, the assistant built into CaseVigil. It cites the provision and the date it was read.
  - Every new case at Parikh & Prasad, PC opens on CaseVigil.
- [VisaVigil](https://visavigilai.com/visavigil/): VisaVigilAI's own immigration-law model. It is not a public chatbot with our name on it.
  - It is trained by immigration lawyers to answer only from primary law, citing every source.
  - It is live inside CaseVigil, where it answers Vigil's legal questions.
  - **How it is trained:**
    - fact-pattern questions written by the firm;
    - expert answers built from the firm's own law library;
    - fine-tuning (LoRA);
    - reinforcement learning (GRPO) that rewards only citations that exist and quotations that match their source.
  - **How it is tested:** each version sits a blind exam it has never seen, with invented law counted. A new version goes live only if it does better.
  - **What stays out of training:** no client facts.
- [VisaVigil Data API](https://visavigilai.com/data-api/): immigration numbers, saved every day and served as JSON.
  - The Visa Bulletin since 2015.
