Founder, 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.
