Extra Capacity When Your Team Needs It Most
Your in-house team is talented — but even the best teams hit capacity. Busy seasons, unexpected case surges, and staff transitions can leave your firm stretched thin. The Case Assistant works alongside your existing paralegals and legal assistants as a seamless extension of your team — handling overflow case preparation so your staff can focus on what they do best. You pay only when there's work, your cost per case is fixed, and you carry zero overhead during slow months.
Immediate Engagement
Client outreach begins within 24 hours of the firm confirming the project. No delays getting started.
Zero Onboarding
No training period. Send a case today and get a file-ready packet back — no ramp-up needed.
Feels Like Your Team

Why Law Firms Choose The Case Assistant

Every case comes with a fixed per-case price locked in before work begins, so you always know your costs and can protect your margins with confidence. And when your team is at capacity, we’re here to scale with you.
Know your per-case margin before you take it on.

Proactive escalation, not surprises after the fact.

Mariana Lopez-Steele
I've spent 15 years in the trenches of U.S. immigration as a case assistant, supporting attorneys through hundreds of family-based petitions, consular processing cases, and waivers. I started The Case Assistant to offer firms a third option — experienced, on-demand case preparation with fixed and transparent pricing, effective and professional communication with clients, and the professional judgment to know when something needs the attorney's attention.
Why Firms Work With Us
Fixed Costs That Protect Your Margins
When you know exactly what a case costs to prepare, and you know what you're charging the client, you know your profit before you even open the file. That's the power of flat-rate pricing. Unlike variable staff costs — where salaries, benefits, and downtime can erode your margins unpredictably — every case we prepare has a clear, fixed cost quoted upfront. Need help with follow-ups or smaller projects? Hourly billing is available too.
Always Say Yes to a Good Case
Every case you turn away isn't just a lost fee — it's a lost relationship, a lost referral, and revenue your competitor picks up instead. With The Case Assistant handling preparation, your firm's capacity isn't limited by who's sitting at a desk. Take on more work regardless of your current workload, and scale back when things slow down. No need to hire more staff!
Professional, Experienced, and Honest About Our Limits
With 15 years preparing family immigration cases, we've seen nearly every scenario. But experience also means knowing when something needs a second look. If we encounter anything uncertain or outside the scope of standard preparation, we escalate it to your office and the supervising attorney immediately. No guesswork, no surprises — your reputation stays protected.
