We have been working regularly with Maggio + Kattar over a number of years with our clients from France and other geographic locations, the services and advice are excellent. The partners are always available and reply rapidly. They share a lot of information and advice. We have organized numerous webinars and our knowledgeable clients on US immigration matters always find they learn more and are given information that other firms do not share. I would highly recommend them.

Immigration Law
I have worked with Maggio Kattar Nahajzer + Alexander on inbound US immigration issues for over 17 years. They are incredibly knowledgeable, professional, and patient with me. Despite their high workload, we always feel like a priority to them for any of our issues, cases or questions. From a cost standpoint, I do not feel that there is a timer going on every time I pick up the phone.

We could not continue to bring celebrated young and established international musicians to our chamber music series were it not for the support of Maggio Kattar Nahajzer + Alexander. It is thanks to them that our audiences take unbiased pleasure at our often sold-out performances. In particular, we'd like to send thanks to Elizabeth Quinn and her team for their support, which allows Washington audiences to have a true and comprehensive insight and discovery into the global state of classical & new music.

Maggio Kattar Nahajzer + Alexander is a terrific one-stop shop for immigration matters. Their reasonable attorney rates combined with skilled expertise and prompt response times make my decision easy when looking for savvy immigration counsel to assist with our business needs.
Immigration Law
I have been working with the Maggio Kattar Nahajzer + Alexander team since September 2012. I work for an international, independent school with an international faculty and staff, some of which require sponsorship to work for us. Since day one, I have found everyone at the firm, from the attorneys to paralegals and business office staff, to be professional, knowledgeable, prompt and thorough. Even though I ask the same questions over and over again, they never make me feel stupid or as if I am bothering them.

Maggio Kattar Nahajzer + Alexander attorneys are extremely professional and know their stuff. I have worked with the firm for almost 20 years through several different companies. The firm's and attorneys' personalities are inviting and not intimidating. They work their tails off to get things done, know their clients (both the employers and our employees they work with), and treat all with respect and like we are the top of their minds. Their rates are very competitive and I do not feel like I am being charged by the word as you get with some other firms.

Our company switched immigration firms to Maggio Kattar Nahajzer & Alexander earlier this year, and so far, working with them has been a real pleasure. MK is very knowledgeable in various immigration matters, and it shows. I connect with MK at least once a day, and they are incredibly responsive (usually within 24 hours) and never make me feel like I'm pestering them with various requests! In addition, they are very approachable; they answer any employee questions in a digestible manner and with the same courtesy they show the company. They are extremely flexible and truly make us feel like we're their sole client. I highly vouch for MK to anyone looking for a new Immigration firm.

I have been employed as an HR Immigration Specialist for the last 8 years and have worked with several different immigration law firms. Maggio & Kattar has by far been my best experience. The attorneys and paralegals are knowledgeable, personable, reliable, and responsive. I have never had any issues with any immigration related compliance, errors, or rejected petitions thanks for the excellent legal assistance from Maggio & Kattar. Their legal fees are also extremely reasonable and it's apparent that they truly care about their clients. I highly recommend Maggio & Kattar to anyone or any corporation looking for help with immigration legal matters.
