  • Katherine Margaret Sinkins

    Maribel is a knowledgeable, dedicated attorney who fights hard for her clients. She has over a decade of experience and knows how to win cases in Immigration Court. She regularly wins cases at the Baltimore MD and Arlington VA Immigration Court and the Immigration Judges respect her work ethic. She also has a lot of family immigration experience and will lay out all the options for a client. She is thorough in her research and her diligence shows in the results she gets for her clients. She is a great listener and is creative in her approach to problematic cases. She stays in touch with her clients on a regular basis and her office staff is very professional. I highly recommend Maribel LaFontaine because of her experience, her ability to relate to her clients and her tenacity. She fights hard for her clients.

    Ms. LaFontaine is my "go-to" lawyer when I seek advice concerning potential immigration consequences for my clients who are facing criminal charges. She is knowledgeable, reliable and responsive. The best evidence of my regard for Ms. LaFontaine's legal abilities is that I have referred two of my staff members to her over the past several years for legal assistance involving their family members.
