NPS 75 in a world of paperwork: How Envoy Global built an AI-powered immigration platform
Envoy Global is a Chicago-based technology company purpose-built for one of the most paper-intensive areas of corporate legal work: global immigration. Founded in 1998, Envoy is not a law firm — it's a software platform with an embedded legal network, designed to let companies manage work visas, green cards and cross-border transfers as an integrated program rather than a stack of case files.
For the legal and HR teams that sit behind every international hire, the thesis was simple. Immigration work is high-volume, time-sensitive and unforgiving of clerical error — exactly the terrain where AI can add the most leverage.
Envoy's engineering and legal teams started by mapping where errors and delays actually originated. The answer wasn't complex legal strategy. It was the hundreds of structured fields on every government form — names, dates, addresses, employer details, job codes — copied between HR systems, client portals and agency filings, each with its own validation rules and its own cost of being wrong.
A single misspelled name or mis-formatted date could delay a visa by weeks and cost a company a new hire. Meanwhile, the platform was already sitting on tens of thousands of historical cases across 30+ countries — a natural training set for AI that could spot the patterns a tired human would miss.
Envoy built AI directly into the case workflow rather than offering it as an add-on. The flagship capability is AI Quality Sensors — machine-learning models that continuously scan forms in progress, flag potential errors, and alert both the employee and the assigned immigration attorney in real time.
Around that core, the platform layers several automation services:
The result is a workflow where AI handles the repetitive validation and data movement, and licensed immigration counsel focuses on strategy, exceptions and anything a sensor flags as unusual.
Envoy's platform now supports customers processing anywhere from 50 cases a year to 5,000 cases across 30 different countries simultaneously — a scale that would be effectively unmanageable on traditional case-file infrastructure. Across its history, the platform has handled more than 30,000 cases for over 2,000 corporate customers.
The customer experience numbers tell the other half of the story. The industry average Net Promoter Score for immigration legal services sits around 25. Envoy Global consistently scores above 75 — a world-class NPS number that the company directly attributes to the predictability, transparency and error-reduction its AI-powered platform delivers to both in-house legal teams and the employees moving through the process.
For corporate legal departments, the strategic signal is that immigration doesn't have to be a manual, law-firm-shaped cost center. When a purpose-built technology company wraps AI around the workflow, the legal function can process more cases, with fewer errors, at a materially better experience for the business — and redirect lawyer time to the genuinely difficult judgement calls.
