Cambridge Immigration Law

Guiding you through your immigration legal journey with competence, commitment, and compassion.

“Ellen was absolutely fantastic throughout the entire process of helping me to receive my citizenship. She took on a case that had several layers over many years that was, until her, very difficult to solve. In two years, with lots of research and work on her part, Ellen was able to successfully bring our specific case to conclusion.

She consulted with family and adoption lawyers to make sure every based was covered and communicated with our family every step of the way. Her honesty and professionalism was reassuring to us as we have little knowledge of the immigration process.

Ultimately, her hard work and commitment paid off and she was able to prevail – we were able to achieve citizenship much sooner than we had expected. Her dedication was unmatched, and we couldn’t be more pleased with the results we would recommend her any time.”

“I started my husband’s case in August 2018 by myself. The process with the NVC was taking longer and longer. In February 2021, with no hope left, I contacted Ellen’s office. My husband’s case was stuck with the NVC since October 2019, but Ellen’s knowledge and help solved the case within two months and My husband entered the US a week ago. Ellen is the best at what she does, she is very nice, kind, and she is the true meaning of a problem solver. She has always been available and easy to reach out to. I highly recommend working with her and I will keep my contact with her for applying for citizenship.”

“I’ve know Ellen since 2017. She is a smart, compassionate immigration attorney. I have full confidence in making referrals to her, especially for clients who have complicated situations. We share an office suite, so I am able to see how Ellen’s clients appreciate the counsel she provides. It is common for clients to stop by to say “hi” or “thank you” months or years after Ellen resolved their matter. In addition to her strong understanding of the law, I am impressed with Ellen’s empathy and I highly recommend her for immigration legal matters.”

“Ellen is a fantastic immigration lawyer. She came highly recommended from a friend, and within our first meeting, I knew she was the real deal. From supporting us when my then fiancé’s status changed and we had to get married that week, through multiple RFEs in the green card process, and now citizenship, Ellen never skipped a beat.
