Litigation

At Altman & An LLP, we represent clients in complex litigation matters in both state and federal courts. Our experienced attorneys combine strategic legal analysis with strong advocacy to protect your rights and achieve favorable outcomes—whether through negotiation, motion practice, trial, or appeal.

We are licensed in New York, New Jersey, and Washington, D.C., federal courts including the Southern and Eastern Districts of New York (SDNY & EDNY), the Northern District of Illinois, various appellate courts, and the U.S. Supreme Court.

Our Litigation Practice Covers:

Immigration Litigation
We represent individuals and businesses in immigration-related lawsuits against USCIS, CBP, and the Department of State. Our team handles claims under the Administrative Procedure Act (APA) and Mandamus Act to challenge delays, denials, and agency inaction. We also pursue emergency relief—including Temporary Restraining Orders (TROs) and Preliminary Injunctions (PIs)—to protect clients facing deportation, wrongful exclusion, family separation, and other urgent immigration issues.

Class Action Defense
We represent businesses against consumer class actions and false advertising claims, challenging class certification and defending clients under state and federal laws.

Civil Rights Litigation
Our attorneys fight to protect civil rights in cases against government agencies and municipalities, handling matters that often draw national attention and involvement from the U.S. Department of Justice.

At Altman & An LLP, we are dedicated to delivering precise, practical, and results-driven litigation services tailored to individuals, businesses, and institutions alike. Contact us to discuss how we can help with your legal challenges.
