John Nahajzer

Like their predecessors, today's immigrants invigorate the U.S. economy and enrich our culture. They also confront labyrinthine statutes, intimidating layers of bureaucracy, and an increasingly sensitive political climate, among other obstacles.

Maggio + Kattar has represented courageous newcomers and their families, in all facets of immigration law, for more than three decades. In the process, we have become the preeminent immigration boutique law firm in Washington D.C. and a respected leader in the immigration law field nationwide.

The firm represents individual foreign nationals, Fortune 500 and other companies, as well as non-profits, universities and diverse institutions. Crafting pragmatic, comprehensive and cost-effective solutions, and embracing the highest ethical standards, Maggio + Kattar has earned an unparalleled reputation for full-service U.S. immigration services. We strive to educate our clients on U.S. immigration law and procedure—and partner with government agencies to provide cutting-edge expertise on the law and its practical application. Our attorneys also perform significant pro bono work and play active roles in immigrants' rights organizations and at legal conferences worldwide.

Through effective representation, Maggio + Kattar makes it possible for our clients to pursue their goal of integration into the social and economic fabric of the United States.

Maggio + Kattar's strategic vision and mission are shaped by our respect for our clients, their important role in our society, and the responsibilities with which they have entrusted us.

Washington's preeminent boutique immigration law firm

Maggio + Kattar is Washington D.C.'s largest full service boutique immigration law firm.   We represent individuals, companies of all sizes in a wide range of industries, as well as non-profits and universities,  across the nation and around the world. Our dedicated team of attorneys and experienced immigration professionals consistently provides expert advice and dedicated client service.

Our clients shape our vision and our commitment to legal excellence

Maggio + Kattar's attorneys are committed to providing pragmatic, comprehensive solutions to each client's individual and corporate immigration needs.  After more than three decades of leadership in immigration law, our attorneys continue to be nationally and internationally recognized as leaders in the field for our creative approaches and zealous advocacy. We believe that immigrants still define and invigorate our nation's economic and cultural life. We are committed to helping foreign nationals, their families, and employers strengthen America through their enterprising spirit, cultural diversity, and quest for a better life.

We are committed to legal excellence and the highest ethical standards and level of client service.  We act as an extension of our clients' human resources and legal departments, by facilitating the hiring and retention of the best and the brightest workers, and ensuring compliance with increasingly complex and frequently changing immigration laws.

We educate our clients and serve our community

Educating our clients and our community is essential to our mission.  It is our view that immigration lawyers are teachers.  We help our clients understand U.S. immigration law and procedure by providing ongoing client education. 

Community service also has been a consistent mission of our firm. Our attorneys do vast amounts of pro bono work.  We are active in immigrants' rights organizations, and we routinely lecture on immigration topics at national and local conferences.
