Attorney O'Reilly was attentive and professional, both during our Zoom meeting and throughout the duration of my case. He is compassionate and connects with his clients' struggles. My case manager, Ms. Monica Lopez, was also fantastic, she constantly kept me updated and responded to all of my inquiries in a timely manner. I highly recommend their team!

Since the beginning the team was professional and responded in a timely manner. We chose Richard as our attorney and he assigned us to work with Monica. Monica always communicated with us and assisted us through the process. Monica completed the forms in a timely manner and we got to complete and submit within 30 days. At the last minute Kelly had to represent us. We were fortunate to work with both Attorneys and both were amazing. Kelly was very knowledgeable and helped us to gather the documents and be ready for the interview. Thank you for all your support.

My husband and I did a lot of research when selecting the right lawyer to help with our adjustment of status case and knew right after our initial consultation with Richard that we were in good hands. His professionalism, expertise, and calm demeanor immediately put us at ease during a very stressful process. That professionalism and experience was consistent across everyone we interacted with at the firm. Ana Hernandez managed our case and she was extremely diligent and highly responsive. Huge thank you to the team! We highly recommend.

about the process to obtain mine and be able to follow her pointed to only one option: remaining apart for the years the process would take, each of us living in different countries, with all the difficulties and burdens that would bring to our lives and our relationship.

Wilner & O'Reilly were the only specialists who offered us an alternative that allowed us, from day one, to be together in the United States while the process was being resolved. This even gave me the opportunity to start building my professional life in this new country while we waited.

All the timelines they gave us were met, and they guided us at every step the process required, showing professionalism and complete expertise from the very beginning.

It’s impossible to express in this short but sincere review the immense gratitude we will always have for this firm for their help, and for fate itself for placing Wilner & O'Reilly in our path. Thanks to them, we were able to achieve our dream: building a life TOGETHER in the United States.

I had an excellent experience working with Monica L and the team at Wilner O’Reilly Immigration Attorneys for my I-90 case—this is actually my second time using their services, and once again, they exceeded my expectations.
From start to finish, they were professional, knowledgeable, and very supportive. Monica was incredibly patient, detail-oriented, and always made sure I understood every step of the process. She kept me updated, answered all my questions, and made everything feel much less stressful. I truly felt confident and well taken care of the entire time.
The whole team, including the staff and secretary, were kind, efficient, and easy to communicate with. Their consistency, dedication, and genuine care for their clients really stand out.
I highly recommend Wilner O’Reilly Immigration Attorneys to anyone needing immigration assistance. I’m very grateful for all their help and will definitely return again if I need support in the future. Thank you again! 🙌✨
