Free initial phone consultation. At the Law Office of Mary L. Field, we provide immigration law services to clients in the Greater Chicago area and throughout the United States from offices in Oak Brook and Gurnee. The complex and evolving nature of immigration and naturalization laws requires a lawyer who focuses and stays up to date on procedures, political issues and the employment environment. Attorney Mary L. Field applies her knowledge exclusively to immigration law.

Immigration matters require strict adherence to time schedules, application guidelines and specific qualifications for both individuals and employers. Permanent visas (green cards) and each type of United States work visa (nonimmigrant visa) have requirements and limitations that we can help you understand.

Ms. Field has practiced immigration law since 1997. She has owned her own immigration law firm since 2002. Our clients are assured of working directly with Ms. Field from start to finish.

Our firm works with a variety of clients, ranging from families, individuals and U.S.-based business seeking to hire foreign nationals. We provide our clients with the resources, knowledge and counsel to make informed decisions in pursuit of temporary visas, permanent residency, naturalization, citizenship and deportation defense.

We will help you understand your rights and provide you with a thorough explanation of your legal options.
