EOIR Removal Defense

We zealously represent individuals in removal proceedings with EOIR.
Removal proceedings are often complex, high-stakes, and deeply personal. Our role is to guide clients through that process with strategic judgment, careful preparation, and strong advocacy.
We represent clients in a wide range of defensive immigration matters, including asylum, withholding of removal, protection under the CAT, cancellation of removal where available, bond-related issues, motions practice, and other procedural or case-specific relief before the Immigration Court.
We also assist clients in evaluating whether relief may be available before USCIS while proceedings are pending, and how that relief may interact with the court process.
