Review Us

Saurabh K.

Attorney Aaron was fantastic. He was diligent and thorough and explained everything about the process as we worked through it. Glad to have selected him and MMH!

Arthur Nugent

Our experience with Beata Leja was exceptional from start to finish. We were aware of every step and status the whole way through the process. Every step was well thought out, reviewed and submitted with no mistakes the first time. We were well prepared for every question before meeting with federal officials and were able to answer every question asked of us without any issues. My wife and I would recommend Beata and firm to anyone needing immigration advice and citizenship advice at a very fair price.

Jair Gudino

Exceeded expectations. Beata and her team were very helpful throughout my whole process of getting an O-1B visa, which is hard to get. They answered all my concerns and needs and questions, ensured that I had the proper paperwork and preparation for my visa process and walked me several times through the necessary steps.

Sudheer Babu

Best services provided by the team with timely response.

Mirella Luiz

Working with Tahreen and the team was amazing. They are all very responsive, empathetic and their expertise went above and beyond our expectations.

Robert Logan

We had the opportunity to work with Aaron Lawee on an adjustment of status case, and everything went extremely smoothly. Throughout the process, Aaron was helpful and informative, and was also very quick to respond to any question or comment that we might have had. We are sure that because of Aaron’s commitment to our case, we were able to move through the process quickly and without any hiccups. We had our green card interview today, and we see the online notice of our approval this evening. Thank you Aaron!

Nikola Greenwood

Aaron did a fantastic job working with us on our K1 and Adjustment of Status applications. He went over and above to reassure us, and get us through some challenging times and overcome hurdles that came up, especially with the delays caused by the pandemic. He is professional, knowledgeable, and he genuinely cares about his clients. Thank you Aaron, for all of your hard work!

Robin McMahon

Our attorney Aaron was friendly, responsive, knowledgeable, and helped to guide us seamlessly through our interactions with USCIS.

Lucas Krivonozka

Highly recommend this firm. Beata has been incredibly helpful throughout my entire journey from applying for naturalization and answering my questions and concerns and ensuring I had all of the documents I needed, to walking me through the interview and what I should bring and prepare for. I was able to walk in confident knowing that I had all documentation that might be needed and that I knew I was well prepared for it. Additionally, her knowledge of the process for LGBTQ+ immigrants was incredibly helpful. I don’t know that I would have been able to do this without significantly more stress if it weren’t for her, which I’m very grateful for.

Arlex Mejia

Aaron Lawee is one of the best immigration attorneys in the country.

Lorenzo P.

The MMHPC Immigration Attorneys had helped many of my family members and me. My process was surprisingly quick. Through the whole process, they had been very professional. Always answering promptly every question that I had. They also were able to accommodate me with Spanish-speaking personal. Special thanks to Magaly Burciaga for all your help.

Fatima Zehra Mecci

She has fought for me and help me achieve my goals. I truly encourage everyone to go to her because she is a phenomenal lawyer and she will do everything she can do help you out

I would like to thank all of the wonderful attorneys and staff with MMH especially Ms Beata Leja, Aaron Lawee

Mi esposo y yo optamos por usar el servicio con MMHPC y quien llevo nuestro caso de migración fue el Abogado Andres Diaz, quien por su parte fue muy amable en todo momento al resolver todas nuestras dudas e inquietudes, es un abogado muy profesional que en todo momento se mantiene al pendiente del caso, incluso con nosotros nos preparo para la entrevista y estuvo con nosotros en todo momento. Quedamos muy satisfechos con el servicio y sin duda alguna lo recomendamos totalmente.


It was a great experience to work with Minsky, McCormick

David Trace

My case has now entered the final stages of the process and has thus been passed on from the capable hands of Miguel Torres to Sandy Ayala.
Miguel has been handling my case since shortly after James Hallagan accepted it. I just want to say that Miguel has been a pleasure to work with. He has been available, thorough, and communicative. He also has a soft manner about him yet he never deviates from the legal course the case necessitates. Thank you Miguel. Your effort and style is appreciated.

Alejandro Monroy

I first met Beata Leja at a fundraiser for university students with undocumented status. For me, meeting her there was a positive and authentic sign seeing her commitment to supporting immigrants whether they were her clients or not. Fast forward 6 months, i had the opportunity to adjust status and reached out to her to take on my case. Her welcoming and patient approach made it easy to connect with her and have a smooth legal process. Her team was stellar in following up, keeping me up-to-date, and confident in my case. It was a seamless experience because she was always detailed and precise in her notes and questions. She also prepared us for the interview and walked us step-by-step which calmed my anxiety. I highly recommend Beata to anyone who needs legal representation. She has your best interest as a professional and at heart. Hire Beata as your next immigration lawyer.

Harish Katta

Beata and Vincente from MMHPC have worked on my H1B transfer petition. They were very professional and answered all my questions on priority. My visa transfer petition was handled very smoothly and Thankfully, with their esteemed service my case was approved very early. I’m grateful that my case was addressed very fast and I’m very much impressed with MMHPC and their services, I’ll definitely reach out to them for future services.

Marcela P Cartagena

I recently witnessed attorney Ana Maria Echiburu Tyrell and assistant Miguel Torres at work when they traveled to a little town called Morton, Mississippi, to give free consultations after the horrific ICE raids took place there. They genuinely cared about each client who came for a consultation. Most of the clients didn’t speak English, but Ana Maria and Miguel managed to communicate with them easily as Miguel also served as an interpreter. This collaborative effort made people –who were already experiencing extremely stressful situations– more comfortable and at ease. In addition, Ms. Tyrell stayed focused as she tried to find every possible solution to the clients’ problems. They listened patiently towards each story. I was impressed with their knowledge and professionalism. I highly recommend them. They are the best of the best!

Aaron S.

Efrain M.

All I have to say is wonderful things about this law firm! My experience was a smooth road thanks to the knowledge and dedication of my attorney Beata Leja. She gave me all the confidence I needed since day one, thanks to her professionalism and realistic explanation of the entire process on my case. I have recommended her services to people that I know personally and they could not be happier with Beata’s help. There’s plenty of shady immigration lawyers out there that only take advantage of people’s desperation, but I can totally suggest this firm for your immigration services. I’m sure all of their lawyers are as professional, but I would recommend Beata Leja; not only she is caring and super smart, but she has also made it to the 2018 list of “40 UNDER Fourty” Law Bulletin Media for Illinois Attorneys, which I’m sure is not that easy to get to unless you have what it takes and she’s got it. She’s also involved with nonprofit organizations, which also shows her compassion and dedication to helping others! Way to go Beata! My respect and admiration for you and your career.

Crystal Varela Galvan

My Husband & I worked with Beata Leja and her team to obtain my husband’s residence. She is absolutely the BEST! I highly recommend her. She is very professional, explains every detail, was patient and very helpful in any questions we had. She made us feel that everything was going to be ok every time we would meet up. We are forever grateful. Thank you Beata Leja!!!!

I give them 10 stars!!!!!

Ana Margarita Arévalo

Abogado Hallagan muy amable y muy apegado a sus casos y sus clientes , excelente persona

Tal Galfsky

Retained their services after my green card case kept getting delayed for over two years. I worked with Beata and she did a fantastic job in getting USCIS to start shifting gears and grant the green card. She was fast to respond and kept her finger on the pulse of the application. Her advice was helpful and accurate and having her on the case did a lot to relieve my stress when my EAD expired and I was waiting for renewal. Highly recommended. Beata’s help was invaluable for my case.

Cecylia Szewczyk

I feel very very lucky to meet Beata Leja (& her team) on my way and be able to work with her. Superior professionalism. I was in trouble, she found a way and took me out of it. Now I am a happy Green Card holder and I can continue developing my career without worries.

Ian T.

Prior to moving to Chicago, my partner and I faced plenty of uncertainty about the visa application process due to our unique family circumstance. However, meeting Beata was truly a turning point in what would have been a daunting process! From the get-go, it was clear that Beata was attentive, caring, and knowledgeable about the entire immigration process. Even when USCIS dropped the ball on several occasions, Beata would always be one step ahead, and would consult with us strategically to figure out a way to move the process forward. If you’re reading this review, you’re probably in a similar situation as we were in, facing doubt and uncertainty about a process that’s overly complicated. All I can say is that you are in the best hands, as we experienced throughout our application. Her knowledge of the immigration process is unparalleled, but it’s really her genuine warmth, and dedication to her clients that’s remarkable. Thank you, Beata!

Emanuele Bianchi

I worked with Beata Leja and her colleagues to obtain my US citizenship. Very professional team and a pleasure to work with. I recently did my oath ceremony!

Y. Hwang

I was a client of Ana Maria Echiburu. She is knowledgeable, straightforward, and most professional. She could explain complex matters in simple language, so I had a clear understanding every step of the way.

Fridder Jahary Llacsa

Ana María Tyrrell is a very fine professional whose advice and knowledge is amazing. I’m glad I got to know her and that she helped me with my legal status. I will definitely keep working with her.

Abhishek Sharma

Beata is a wonderful professional who help me immensely against all odds. I had an EB based green card case but I was running my own business. All the “so called” leading immigration lawyers were telling me it is impossible to do and the quoted me an enormous amount of money. However, Beata looked at my case and said that she is very confident of resolving it. She charged a fraction of the price that other lawyers were asking and took care of the case to completion.
I am very thank you to her. She is a wonderful human being and a very knowledgeable lawyer who is diligent, honest and trustworthy.

They are the best immigration lawyers and very cost effective & efficient. Beata is the most astute lawyer I ever met. Her and her staff have tremendous knowledge, diligence, and ethics. She will make sure that you get the best service possible. Very very good folks. I highly recommend anyone who needs immigration services.

Chika Mignani

Great law firm… Highly recommended!

Roman J.

I had a complicated case related to employment-based greencard where my paperwork got screwed up by the previous attorney.
The mistake was a clerical error but could have had serious consequences on my stay in the country.

Derek from MMH recommended very strategic approach that gave me extra time to get everything sorted out. It has worked out very well.

The staff of MMH is very professional and committed. They respond well to questions and explain everything in detail. It has been great working with them.

Saul Ilacsa

Working with Ana María Echiburu Tyrrell was a great experience. She helped me switched my visa status from student to a R-1 visa. Her knowledge and experience made me feel very comfortable knowing I am in great hands. Will definitely recommend her to my friends, family, and more.

Brian H.

Beata was able to help me in a very complicated case. I started working with another attorney from a different law firm. Things were not going well until I moved my case to Beata’s practice. She is professional in every matter and very easy to communicate with. What is most important she is up to date with all changes in the law( which as I experienced is not always the case with every attorney) and she knows how to use her knowledge to your advantage.

Carlos De Leon

They are doing great work!

Norka Cirino

Muy buen servicio en inmigración.

EnRico Wallace

I wish we could yell from the rooftops regarding Beata Leja and this firm. Professional, always responsive and expedient in communications. We will ALWAYS use MMHPC no matter where we move. We are now in Houston because of a promotion and learned quickly that we were blessed to find this firm and will always deal with Beata!

Masha Les

My experience with Beata Leja was exceptional. Attorney Leja and her team have done an outstanding job in my H1-B petition, she was working on my case even after business hours because it was time-sensitive. They also did a fantastic job advising my employer on how to handle the case correctly and informed me the first minute they knew about my application results. I would have no hesitation in recommending Attorney Leja and Minsky, McCormick & Hallagan, P.C. to anyone who is looking for immigration assistance.
