Case Study
Large Global Immigration Firm
Overview
A mid-size travel and hospitality platform faced significant challenges in managing customer bookings and inquiries due to increasing demand and reliance on manual processes. The company partnered with Wizr Labs to leverage multi-agent architecture and Voice AI agents, bringing remarkable improvements in customer satisfaction and operational efficiency.
The Challenge: Streamlining High-Volume Immigration Letter Creation
As the world’s largest immigration firm, the client manages thousands of visa applications annually, including H-1B, L-1B, and Canada immigration cases. A critical part of the process involved creating support letters for each application — a task that required approximately 4 hours per letter. With the sheer volume of requests, especially during peak filing seasons, this manual approach became a bottleneck that impacted service timelines and operational efficiency.
“Automating immigration support letters reduced drafting time by 75%, enabling us to generate 20,000+ documents annually with higher accuracy—without increasing headcount."
The key challenges included:
Time-Intensive Process
Each letter required meticulous drafting, review, and quality checks, leading to long turnaround times.
High Volume of Requests
With over 20,000 support letters produced annually, scaling the manual process became increasingly difficult.
Error-Prone Drafting
Manual drafting left room for human errors, potentially affecting compliance and client satisfaction.
Inconsistent Quality
Varying levels of experience among staff led to inconsistencies in letter quality and adherence to client standards.
Scalability Constraints
The firm struggled to scale operations without adding significant headcount.
