Wonderful work!
We reached out to Mark Davidson for assistance with our immigration case, and it was one of the best decisions we could have made. The team demonstrated exceptional professionalism and deep expertise in their field. The lawyers were always ready to answer any questions, significantly reducing our stress throughout the process. Mark handled our case with assistance from Ruslan. The preparation for the court was conducted at the highest level: every detail was meticulously thought through, allowing our case to be presented most effectively. Thanks to their efforts, we won the case, which was a huge relief and joy for our family. I highly recommend this firm to anyone seeking competent and reliable legal support. Many thanks to the entire team for your hard work and support!

Smart. Strategic. Go-to person. The BEST.
I hired Mark in 2015 when my initial application for asylum was referred to the immigration court. He agreed to take my case and since had built a case that my previous lawyers hadn't even thought about. My court hearing was delayed 6 (SIX!!!) times and each time Mark would update my case with the country conditions and get the updated affidavits from the experts. He asked for numerous supporting documents and proofs to strengthen my case and I had two lawyers before and those never asked for anything remotely like that. Each time he would work with me to tell me what kind of information I needed to provide and throughout this time he would always respond to my questions in a timely manner. He is succinct in his replies, but those are always to the point. He charged a fixed price for the whole case and even though the case was delayed so many times and he had to redo a lot more, he never charged more and honored our contract. My case was at a court with a very low rate of asylum granted and I was very, very anxious about the outcome. He told me "to trust the system" and to trust his judgment of my case's strength and to focus on the bright side. His reasoning, vision, and so many years of experience gave us all comfort in our case. Finally, in 2024 we had our individual hearing and we obtained our asylum. I can't thank Mark and his team enough for the work they've put forth and the guidance they showed throughout our journey that lasted over 8 years. If Mark takes your case, then it means that he sees the strength in it and I'd trust his judgment and the strategy he picks to position your case. I am aware of many friends who took Mark as their lawyer and they all were very satisfied with the outcome. On a personal side, he is a person with a great heart and compassion. I'd recommend Mark 1000 times over to any asylum seeker who needs professional help. Thank you Mark and your team!

The key to success
My family recently won our immigration case - undoubtedly due to Mark's and his team's exemplary professionalism. From our first meeting, Mark showed a very thorough approach to every single detail of our case, making sure that we are overly prepared for and confident about the hearing. If you would want to maximize your chances to win the immigration case, I highly recommend working with Mark Davidson and his team.

Simply put - the best
We reached out to Mark Davidson's office regarding our ongoing immigration case after working with two different immigration lawyers that seemed disinterested and unprofessional. I'm glad we kept looking for competent legal help and ultimately found it! Mark and his team are simply the best. We were helped, properly guided and always felt valued. The communication was always clear and concise, we really felt that our lawyer cared and was doing a great job. Mark's team was awesome! We're definitely going to stay in touch for future immigration needs, and I would HIGHLY recommend Mark's services to anyone.

Probably the best lawyer in Chicago
Mark Davidson is a probably the best lawyer in Chicago, even if he do not took my case he give me advice that let me stay and get me citizenship. Would recommend him to all who need help. If you ready to hear true about your case and not promises that everything going to be fine go to Mark.

A five star attorney that you should hire
Today is the day when I become a U.S.A. citizen and I have to thank for that to attorney Mark Davidson. I have approach him in the past with a complex case when because of some false accusations I was one step away closer to deportation. His advice has helped me to sustain my case in court and mantain in the same time a clean path for citizenship. After this crazy ride I finally have the opportunity to continue my life in U.S. as a citizen and teach my american born child about the the values of this country. A country that was built by immigrants that like me have face discrimination and tough challenges in life. However they never stop believing in the great “American Dream”. This dream is the roots of our country and this diversity is what makes America great. In today’s dark immigration climate however you need an attorney like Mark by your side. Resonable priced, and with a high level of professionalism and experience you can’t be wrong by retaining his service. I already highly recommended him to all my friends and family! Thank you for all your help.

knowledgeable, dedicated and most of all honest- an immigration attorney I would recommend to anyone!! Thank you Mark!
We couldn’t have been happier with the help and assistance we have received from Mark every step of the way during our immigration process. We have had two different large immigration firms representing us prior to Mark, neither one of which was able to be nearly as creative in finding solutions in tricky and complex immigration case, nor as dedicated. From our initial meeting with Mark, he was very diligent, but also straight up and fair about what our possibilities are, and for the first time since we started our process we felt like we were being in good hands. He gave us precise directions and always set realistic expectations, with a good strategy in place but without making false promises, which was refreshing. We went through J-visa process, H1B applications, permanent residency application and through each one of these processes we felt like Mark and Leigh always had a back-up plan in case something didn’t work out, within the limits of the law, and there was always specific guidance on their part, which we were missing with all of our previous representatives. We feel beyond happy and also fortunate that we had an attorney who through his thoughtful and dedicated approach, helped us reach a permanent residency status in relatively very short period of time. I would sincerely recommend Mark to everyone seeking detail oriented, knowledgeable, experience and yet carrying attorney to represent them in their immigration case.

Excellent Immigration Processing of my Petition for my Same Sex Spouse
As soon as the Supreme Court declared the Defense of Marriage Act to be Unconstitutional in 2013, I contacted Mark Davidson to request Residency for my spouse. Davidson and Schiller worked efficiently as a team to guide me through all the steps (the I-130, the Hardship Waiver I601, and finally, the Consulate Interview. This was a nerve wracking time for me and my spouse and I was so nervious when we went to Juarez to have the interview with the consulate. I was so worried that the Consular staff wouldn't like something in the paperwork that we had prepared and they would reject my petition and my husband wouldn't come home. As it turned out, Mark's team had followed all the steps in the process perfectly, they gave us a package of paperwork arranged exactly as the consular personnel wanted, and he received his visa within a week. I give Mark Davidson 5 stars and I have already recommended him to many of my friends, including my co-worker Tom Bloom, who brought his son Sam to Davidson where he successfully got his wife's green card. I can't say enough about how thoughtful, organized, and efficient, the services of Davidson and Schiller were and I will continue to recommend them to anybody who asks.

Thank you Mark!
The least I can do is to provide a fair review. My journey to the States was very easy thanks to Mark. He worked on my visa two years ago - it was approved within a month. In July 2016 Mark accepted to take my case for perm residency. Mark and his assistant Leigh, much obliged, have been more than helpful to me in a stressful time where a new administration has been taking over and the uncertainty for immigrants is growing. Mark, thank you very much. I have been recommending Mark to anyone seeking a phenomenal lawyer's advise and help.

Mark knows what immigration law is!!!
So I found Mr. Davidson after I was denied by asylum officer and they sent me to the court. My case is complex and complicated, but 15 minutes was enough for him, to find mistakes of my previous attorney and understand my story. He is not the cheapest lawyer you will find, but every cent you will pay to him will be paid off, believe me!! Mark was very honest right from beginning and generally he is a nice guy.

The Dean of the Chicago Immigration Bar
A lawyer myself, and having worked with recruiting lawyers in Chicago for more than 20 years and therefore having access to many sources of information, there is no question that Mark Davidson is the Dean of the Chicago immigration bar. The many recommendations I initially received of him, were confirmed in four years of working with him to bring my wife back to the United States in obtaining first a green card and then a waiver of the 10 year statutory bar. You are in excellent hands with Mark Davidson, however inhumane and frustrating the U.S. immigration laws may be. Unlike some immigration lawyers in Chicago he does not gouge his clients on fees. His fees were reasonable to a fault. He has a great team working with him. I recommend him extremely highly.

Awesome immigration lawyers
Used Davidson & Schiller for changing status to Conditional Resident, then Permanent Resident and eventually US Citizen. Since they are in downtown Chicago, their office was easily accessible. They helped me go through the process with ease and answered any questions I had. I did had some hiccups in my case (USCIS fault), however they kept on top of things to make sure the case won't get affected. They sometimes have latency in their replies, but eventually do get back to you. Other than that, you can't go wrong with them.

best lawyer ever
I come to him one month before my green card's lottery deadline and thanks to his professionalism I got it in time. Other lawyers said it is impossible to do anything with my case to be successful, well Mark this seemingly impossible case made possible.

Great immigration lawer
I have hired Mark few yrs ago to bring my daughter from Republic of Georgia. He did what other lawers didn't even knew was possible and got my daughter in US in no time. And now he also handled my immigration case with great knowledge and proffecion and got me a green card when I thought I would of been deported. Thank you Mark. I would recommend Mark Davidson to anyone who is looking for a good attorney, becouse I know how hard it is to find one who gets job done.

Awesome lawyer with awesome staff! I found him on this website when I needed a second opinion about my temporary Green Card (when my first so-called lawyer messed up my case and had me apply for a waiver that he did not even filled properly and to top it of I found from Mr. Mark Davidson I DID NOT NEED- that put my case on hold for 1 YEAR) . I fired my 1st lawyer and I hired Mr. Mark Davidson and in 3 WEEKS, thanks to Mark, I had my Green Card in my hand. Mr. Mark Davidson and all his staff were VERY PROFESSIONAL, ,patience,worth my TOTAL TRUST,easy to communicate and get in touch with,affordable rates and I could continue with the praise forever! That is the reason why I ask him to represent me again for my permanent Green Card last year and I will continue that this year when I'm going to apply for citizenship! My advise to anybody looking for an immigration lawyer: Do not make the same mistake that I did when I hired my first so-called lawyer :from the money point a view.I was told by my friends that lawyer form downtown are more expensive and they all do the same! NOT TRUE!!! My 1st layer ended up charging me much more than Mr. Davidson! I am going to be grateful all my life to Mr. Mark Davidson and all his staff :especially Mrs.Olga, Mrs. Yllca !
