Immigration Attorneys Licensed in Connecticut & New York.


We are a purpose driven practice.


Founded June 1980 as a general practice, with the idea of helping and advocating for people who could not do so themselves. Originally, the practice began with a little of everything. Founder Maria Luisa de Castro Foden had a wall of file cabinets - one cabinet for divorce, one for criminal, real estate, and one small drawer for immigration petitions. Slowly, but surely, that one drawer for immigration grew to a cabinet, then two cabinets, then three. Today, nearly 40 years later, immigration law is the focus and specialization of our practice.


Guiding Principles

Three considerations guide how we craft a strategy for your case:

  • Time. Many times, there are multiple ways to arrive at a desired result;

  • Cost. We choose the most cost efficient process for our clients; and

  • Presentation. We choose a strategy that best suits our client’s goals and is an accurate representation of who they are.

Edwin D. Colon

Attorney Edwin Colon represent clients in all aspects of immigration law, including family immigration, citizenship, removal defense, consular processing, waivers of inadmissibility, and appeals. 

Immediately before joining De Castro Foden, Edwin was an associate attorney in the Education Law Department of a mid-size regional law firm representing boards of education.  In that role, Edwin engaged in all facets of litigation on behalf of boards of education including: special education, student discipline, discrimination, harassment, Section 504, ADA, Title IX investigations, restraint and seclusion, student data privacy and general education matters. 

Immediately before that, Edwin was an attorney at the Center for Children’s Advocacy (“CCA”) a non-profit law firm affiliated with the University of Connecticut School of Law. At CCA, he served as the inaugural Director of the Immigrant Children’s Justice Project, directed the School Based Legal Clinic at Harding High School in Bridgeport, and worked as an attorney in the Team-Child Juvenile Justice Project. Edwin was successful in representing dozens of undocumented minors who fled abuse and neglect in their home countries and obtained special findings that allowed them to apply for Special Immigrant Juvenile Status (“SIJS”) which allowed them to remain lawfully in the United States. As a result of this work, Edwin collaborated with the Connecticut Probate Court Administration in drafting and securing passage of Conn. Gen. Stat. § 45a-608n, which codified the federal SIJS language into Connecticut law and established path for residency to countless immigrant minors. In addition, Edwin established training seminars and supervised over 100 pro-bono attorneys and immigration practitioners from major law firms to solo practitioners throughout Connecticut on Special Immigrant Juvenile Cases.

Edwin has received numerous accolades for his contributions to the legal profession: James W.

Shayna T. Williams

Attorney Shayna Williams leads our practice in pursuing waivers of inadmissibility. An Indiana state native with Cuban roots, Shayna obtained her Bachelor’s degree at Indiana University and her law degree from DePaul University in Chicago in 2005. After law school, she began practicing in criminal defense and divorce, but was called toward the practice of immigration, which fulfilled her purpose of social advocacy. Shayna joined De Castro Foden in 2014, and has extensive experience in adjustment of status, naturalization, and special immigrant juvenile status.

Following the promulgation of the provisional waiver of unlawful presence and its expansion in 2016, Shayna has become highly specialized in the provisional waiver of unlawful presence, Form I-601A, and focuses on this important waiver as her expertise in the practice of immigration law today. Shayna has successfully achieved more than 1000 approvals of this unique waiver of inadmissibility, which ensures and protects the unity of families of undocumented people who have spouses or parents who are residents or U.S. Citizens.

A zealous and compassionate attorney with a social advocate twist, Shayna dives deeply into the lives of our clients to present a fulsome record of the equities that USCIS should consider in each case.
