I cannot recommend Wilner & O’Reilly highly enough! I recently received my green card, and the entire process was handled with the utmost professionalism.
Attorney Richard Wilner is incredibly knowledgeable and made us feel confident from day one. His expertise in immigration law is evident, and he provided clear, honest guidance at every step, there’s a reason he is the best to do it so look no further

Tamara was a massive help in preparation for the interview process and got me and my wife 100% ready to get it done

A huge thank you to my case manager Ana , who was always organized, responsive, and patient with all my questions. She kept me updated throughout the entire process which really helped ease the stress. If you are looking for a firm that actually cares about its clients and gets results, look no further. 110% recommendation!
Wilner & O'Reilly Are the one for you!!

This is the top Immigration Law firm in the nation. They helped me almost a decade ago with my DACA case and helped me all the way through my citizenship process (which I obtained successfully) because of them. They are very professional and are phenomenal when it comes to communication and getting the job done. They’re good, big celebrities go to Wilner and O’ Reilly for their immigration cases.

I want to express my sincere gratitude to my attorney and my case manager, Karina, for all their help and support throughout my immigration process. From the very beginning, they were kind, patient, and always willing to answer my questions. Karina was incredibly efficient and made sure every document was prepared correctly.

During my interview, attorney Tamara was there with us, and her presence made me feel calm and confident. She was supportive, knowledgeable, and guided us through the entire process with care and professionalism.

Thank you for helping me and my husband achieve this important step. I highly recommend them to anyone going through the same process!

I can’t thank Wilner & O’Reilly enough for all their amazing help with my family immigration case. Especially in this current administration with all that is happening. From day one, they made everything so easy to understand and handled the whole process quickly and efficiently. I really appreciated how responsive they were — always getting back to me right away and making sure I felt supported every step of the way.
Thanks to their hard work and dedication, everything went smoothly and faster than I expected. My family and I are so grateful for their kindness and professionalism.

Thanks to the law firm Wilner & O'Reilly, APLC, I was able to obtain my permanent residency. It was a long process, but when attorney Michael Jurado got involved in my case, he gave us the confidence and security we needed, and the process moved faster. 'My case was one of his first cases,' and even though he couldn't accompany me to my interview, I am very grateful to him. Instead, attorney Kelly O'Reilly took his place and also made me feel very secure and positive. A big thank you to everyone who was involved in my case. Thank you, Wilner & O'Reilly

Gracias a la firma de Wilner & O'Reilly, APLC pude obtener mi residencia permanente, fue un proceso largo, pero cuando el abogado Michael Jurado se involucro en mi caso nos dio la confianza y seguridad que necesitábamos y se movió mas rápido "mi caso fue uno de sus primeros casos" y aunque no me pudo acompañar a mi entrevista estoy muy agradecida con el. En su lugar fue el abogado Kelly O'Reilly quien también me hizo sentir muy segura y positiva, muchas gracias a todos los que estuvieron involucrados en mi caso, gracias Wilner & O'Reilly.

Wilner & O'Reilly are highly professional. The case manager assigned for our CRBA case, Alondra M Mercado had been highly professional, friendly, helpful, and knowledgeable. I applied for my Child's CRBA from Pakistan and hired their services to do this. The Attorney and our Case Manager were very clear about the case, gave us clear and specific direction, list of required documents, and help us successfully acquire my child's CRBA and passport.
They are jot the money maker type. Will give you the best advice. I would highly recommend their services.

I had an outstanding experience with Kelly and the entire team of Kyler and O’Reilly Law Firm during my citizenship process. Their team is professional, knowledgeable, and truly committed to their clients.

I especially want to highlight Karina, Kelly’s assistant. She was absolutely incredible throughout the entire process. Karina always made sure to get back to me the same day with clear and relevant answers to any questions I had. Her responsiveness, professionalism, and ability to keep everything organized gave me complete confidence that my case was in good hands. She is an excellent communicator who made what could have been a stressful process feel manageable and straightforward.

Tamara, the attorney who worked on my case, was equally impressive. She ensured that every detail was carefully reviewed so that nothing was missed. Her attention to detail and dedication helped move my case forward quickly and without any discrepancies.

Thanks to the teamwork of Kelly, Tamara, Karina, and the rest of the firm, my case was approved smoothly and without delays. I highly recommend Kyler and O’Reilly Law Firm to anyone seeking reliable and attentive legal representation.
