Borowski Witmer Immigration Lawyers is a comprehensive immigration law firm with offices in Buffalo, New York and in Northern Virginia. We have been featured on news media outlets including CNN, NBC, ABC, Time Warner Cable News, The Boston Globe, and The Buffalo News. Our lawyers are licensed to practice before the Immigration Courts, USCIS, and the Board of Immigration Appeals in all 50 states.

We also handle federal litigation matters including, perhaps most importantly, habeas corpus petitions to secure freedom for detained immigrants, as well as petitions for writs of mandamus (to force action by immigration authorities in the face of undue delay or other violation of the law).

Jurisdictions in which we handle habeas corpus petitions and petitions for writs of mandamus: New York, Virginia, Texas, Washington, D.C., Maryland, Colorado, New Mexico, Indiana, Pennsylvania, New Jersey, California, Tennessee, West Virginia, and Florida.

We litigate Petitions for Review in the federal appellate courts. We are licensed in the following circuit courts of appeals: 2nd, 3rd, 4th, 5th, 9th, and 11th.

We also handle post-conviction motions (motions brought under CPL 440.10) in New York State

Since the beginning of the second Trump administration in 2025, Mr. Borowski has litigated hundreds of habeas corpus petitions in the Western District of New York, and is responsible a large portion of the habeas litigation and developing caselaw in that district as well as in the Northern District of New York.

Our immigration court practice focuses primarily on the Batavia Immigration Court and the Buffalo Immigration Court, but we also provide representation before the Annandale and Sterling (Virginia) Immigration Courts. We have handled matters nationwide, winning cases from Arizona to Texas to Massachusetts.

Our firm is, for the time being, no longer handling employment-based immigration matters. In the past, we handled numerous employment-based matters, including TN/NAFTA visas, investor and managerial (L) visas, and even labor certifications, due to our proximity to the northern border. Due to the current administration’s war on immigrants, we are focusing primarily on detention matters and immigration court representation, where there is the most need and the fewest competent attorneys willing and able to provide representation. However, we continue to represent clients in family unity cases including family-based immigrant visa petitions, naturalization (citizenship) cases, victim-based immigration benefits applications such as VAWA, Special Immigrant Juvenile Status (SIJS) for minors who have been abandoned or neglected by a parent, including pursuing guardianship proceedings in family and surrogate’s courts in Western New York.

Our attorneys are willing to tackle the tough cases and think outside the box. Our reputation speaks for itself and results in a very high demand for our services. Unfortunately, we do not have the resources to take on every client that contacts us, and we apologize in advance if we are unable to take on your matter due to a lack of capacity. In those instances, we will attempt to refer you to other lawyers who may be able to assist you.

There is no such thing as a routine legal matter. Every case is unique and deserves the undivided personal attention of a strong advocate with your best interests at heart.

Call us today at 716-330-1503 (NY) or 703-649-3225 (VA) to schedule a consultation.

What Our Clients Have Said

Michael Kanyambo, Federal Litigation Matter

The best immigration law firm and best immigration lawyers in the country I would recommend to anyone who is in removal and deportation proceedings. I have found in them a high level of professionalism, knowledge and compassion. Thank you very much for assisting my nephew who was detained by ICE. God bless.

Walter Neville, Federal Litigation Matter

Mr Borowski was highly recommended by several other Immigration Law Firms to handle a difficult case for a family member. Mr. Borowski treated me like family, and was able to bring the case to a successful conclusion. It was a very difficult Immigration detention case.. Without his expertise, experience, and compassion the desired outcome probably would not have been possible.. During the case, a critical issue of proper medical treatment became an emergency, in need of a quick response. Mr Borowski immediately took action, and restored the medical treatment with a Federal Court Judge Order.. While the case proceeded in court, I was able to sleep at night knowing the best possible attorney was on board, handling the case.. That peace of mind is priceless.. Thank you

Onur Gezer, a Deportation Defense Client

First, let me point out that what started out as a nightmare immigration situation for me quickly turned into a manageable experience. I have the Borowski Law Firm to thank for giving me the re-assurance and hope that was greatly needed when I chose to hire them to handle my case. Questions were answered promptly and time was taken to explain slowly and clearly so I could understand the legal terms. Matthew put in the extra effort to ensure that paperwork was completed and turned into the court within hours of us contacting him prior to him beginning his weekend so we could have some piece of mind that the process was beginning. Matthew and Ryan were able to foresee how our case would end and the outcome was better than we expected. Immigration matters are very complex and I highly recommend the services of Matthew and Ryan to handle anything that you may need involving your immigration needs. They truly showed a genuine compassion that is rare to find with many attorneys. I deeply appreciate all that they did for me and my family and will never forget them because they stood out of the crowd by going above and beyond in my particular case. The Borowski Law Firm is the first I would call or recommend.

Jarrad Roeder, a Spousal Green Card client

Ryan and Matthew managed my fiancee's (and now wife's) immigration into the United States from start to finish. They really made what is a terribly difficult process quite easy for the two of us. Even as last-minute issues popped up, they were extremely accessible by phone and handled everything with professionalism. Definitely glad that we decided to engage their services.

Keydy Fonseca, Family Member of a Deportation Defense Client

Mr. Borowski is an excellent attorney... I was able to reach out to him when needed, as he was always attentive and quick to get back with me. He initially explained the process in detail, and did not create any false expectations. He was always professional. He made everything much easier for the family... Once my daughter's dad was out of the detention center, I received a call from the attorney to further explain the next step. I truly value his professionalism and attention. We would definitely recommend him to handle your case... Mr. Borowski's representation was immaculate. I strongly recommend the office of Borowski Immigration Law.

Marta Marciniak, a Marriage-Based Green Card Petition Client

Mr. Borowski was very helpful with my petition for permanent residency based on my marriage to a US citizen. He was very understanding and cooperative when it came to payment options that I could afford and handle at the time when I was filing... Very friendly and knowledgeable. Made the process smooth and I didn't have to worry about filling out all those forms all by myself. His assistant came to our interview at Immigration which also helped in that somewhat stressful situation.

Faiz Sinahi, Fiancee of a Successful Asylum Claimant Represented by Borowski Law

My fiancee was detained by ICE. And she wanted to file for asylum... I called and went to different lawyers... I spent so much money just to speak to them about my fiancee's situation. Some of them didn't wanna take her case and the rest wanted so much money up front. They were telling me that her case was so hard and there is a chance that she will get deported... I was so stressed out... until I found Mr. Borowski... He took her case and went to visit her a couple of times at the facility. He gathered every document to get ready for the court day... When that day came I prayed and prayed that they will win the case. Time was moving so slow, I was so nervous. Until late afternoon my phone rang and I saw Mr Borowski's cell number. I answered the phone and my fiancee said where are you, aren't you coming to pick me up?... She said it's me, we won the asylum... I was so happy, tears were coming out my eyes, ran out of words didn't know what to say except thank god and thank you Mr. Matthew Borowski for everything you have done. You are the best lawyer.
