Our team

The team at Cambridge Immigration Law works together with our clients to achieve their immigration goals. We offer empathy and transparency throughout your immigration legal process so that you can focus on your professional, academic, family and personal goals. While we serve clients nationwide and internationally, we also take great joy in our connection to the Cambridge community where we work, live, and raise our families. It is our pleasure to work with clients who are also our neighbors.

You start your immigration journey with Cambridge Immigration Law with a consultation with an attorney.  Once you and the attorney decide on a legal strategy, you can choose to hire our firm to represent you.  After signing a Representation Agreement and securing payments for legal fees, you begin your work with our legal team.  Our legal team includes our supervising attorney, managing attorney, paralegals and legal assistants, all whom work on different aspects of your case and who communicate with you through the various stages of preparing your case.  Using client-friendly online tools such as  Pipefile, Clio and Docketwise, our legal team prepares your legal case with your input and approval.

We work hard to make your immigration case easy for you. Use this easy guide to help you organize the documents that you would use if you are eligible to submit an application for a marriage-based green card application.
