Former USCIS Attorneys, Now on Your Side of the File

Whitaker & Warburton was founded by two attorneys who spent their careers inside U.S. Citizenship and Immigration Services. Kristin helped write the standard that governs National Interest Waivers. Melissa advised the officers who adjudicate employment-based petitions and defended the agency's decisions in federal court. They built this firm to bring that knowledge to the other side of the file.

How We Work

A Boutique Firm, by Design

We are a small boutique firm that prides itself on individualized attention to every matter we handle. That is how we work, and it means we are not able to take every client who asks us to.

Before we accept a case, we review it honestly and give you candid feedback on the viability of your profile. If the evidence is not there yet, we will tell you, and we will tell you what would change that.

When we do take a case, it is built against the review it will actually receive. Every petition is read the way an officer will read it, and every criterion is tested against what the evidence in the file will support. If a decision comes back that cannot be reconciled with that record, we are prepared to challenge it in federal court.
