Jennifer Mazzei, is a graduate of Hofstra University School of Law and practices in the areas of criminal defense and immigration. Prior to co-founding The Law Offices of Mazzei & Polk, L.L.C., she was an Assistant District Attorney in the Nassau County District Attorney’s Office for over five years.  During that time, she prosecuted felony and misdemeanor crimes, conducted wiretap investigations, worked closely with detectives and police officers and assisted in several federal investigations.

Jennifer began her career in District Court where she handled traffic violations, Driving While Intoxicated (DWI) related offenses and many other misdemeanors including assault, aggravated harassment, reckless endangerment, sexually based offenses and drug related offenses, trying several of them to verdict and conducting many evidentiary hearings in the process. 

Rising up the ranks quickly, Jennifer was then promoted from District Court after only one year and was assigned to the Special Victim’s Bureau, where she exclusively prosecuted domestic violence cases for approximately one year and tried several of them to verdict.

Jennifer was then promoted again to the Grand Jury warrant rotation where she presented numerous cases to the Grand Jury and secured indictments in nearly every case. In addition, during that time, Jennifer assisted police officers and detectives in determining what crimes to charge defendants with and advised them on how to handle certain legal situations. Jennifer also handled all requests by detectives and police officers for search warrants in matters including homicides and vehicular manslaughter. 

Again rising quickly, after approximately one year, Jennifer was again promoted to the elite Organized Crime and Rackets Bureau where she worked closely with local law enforcement as well as federal agents while she investigated and prosecuted cases involving organized crime, sexual abuse of children, child pornography, drug manufacturing and distribution, violations of the New York State Tax Law, witness tampering, gambling related offenses and enterprise corruption.  On more than one matter, Jennifer worked closely with the United States Attorney’s Office for both the Eastern District of New York as well as the Southern District of New York to prosecute numerous defendants. While assigned to the Rackets Bureau, Jennifer conducted investigations involving court authorized eavesdropping warrants (wiretaps) on approximately seventeen different phones, earning her multiple awards from the federal government's various agencies including the United States Attorney's Office for the Southern District of New York.

Great attorney!
My husband and I hired Jennifer Mazzei to file an immigration petition. Jennifer was extremely helpful, approachable and down to earth since day one, she always took the time to explain every detail and clarify every doubt. I reached out to her several times, and she was always quick at replying and willing to answer every question we had. When she was gone for personal reasons, it was easy to reach out to Jim Polk who was extremely helpful as well. Jennifer made the process very easy for us. Our petition was approved in 11 months without any issue, and we would surely recommend her to anyone in need of an immigration attorney.

The best immigration lawyer!
I highly recommend Jennifer Mazzei as your immigration lawyer. Due to her excellent knowledge of immigration law I became a permanent resident of the U.S. From the beginning, Jennifer explained to us all the steps we have to go through and the process went as expected. During my entire immigration process, Jennifer was highly professional, very meticulous and caring. My husband and I are extremely grateful to her as she was always there when needed. Jennifer sure is truly the Best Immigration lawyer and a wonderful person. I recommend her services to all people who need immigration assistance. Thank you again Jennifer for everything! You are an outstanding lawyer!

Excellent results for a difficult case
Ms. Mazzei is very bright, an excellent attorney. We hired her to defend my son on a misdemeanor and to me, his dad, it didn't look too good. But she showed up in Court totally prepared and somehow managed to get the charge dismissed (after probation). Her results exceeded our expectations. Hopefully we never are in this position again, but if we were, we'd hire her again in an instant.

Highly Reccomend
Jennifer treated me with the utmost respect and dignity during my time of crisis. She is reliable and dependable. Her professionalism, understanding, and compassion are a rarity in most attorneys, but Jennifer had all 3 qualities, making her a unique criminal defense lawyer. I would highly recommend Jennifer to anyone in need.

Immigration
My husband and I hired Jennifer for help with our petition for my husband's green card. The paperwork required for the green card can seem overwhelming, but she made it all so clear, simple, and easy. She provided us with detailed lists of the paperwork we needed to gather, which made the whole process so much easier for us. She was willing to meet with us as many times as was needed to go through everything with us. We appreciated her dedication to organization and her expertise advice. She is very professional, yet very personable and down to earth. I highly recommend her!

My wife and I just had a preliminary consultation with Ms. Jennifer Mazzei and Mr. James Polk. We were very impressed with each of them. . They took their time to listen to us and were very thorough in explaining the hurdles and limitations of our situation. And are honest counselors. We recommend them to all who read this. It's very hard to find lawyers like them. I met many lawyers in my life and these two touched us in a special way.

During the consultation, Jennifer was very informative, very thorough. After talking to other attorneys, her professionalism and detailed approach during the consultation, convinced me she was the right representative for my case. I highly recommend Jennifer.

Jennifer Mazzei was Victorious!
I had an issue going back 30+ years, I spoke with 5 other lawyers and not one could see my point. I had a brief phone call with Jenn, she was able to acquire documents that were needed, saw my concerns, and proceeded to work on my case. Her sharp mind, acute eye and experience in the practice of law, gained me the victory I have been chasing for decades. She was prompt to return phone calls, friendly and polite. I am completely grateful.

Highly Recommended!
Jen had initially helped me file my green card petition (based on my marriage) in 2015. She was very thorough and I had no trouble getting my conditional green card. Unfortunately, my husband and I parted ways 2 years later and I found myself reaching out to Jen again, this time from Arizona, where my husband and I had moved to since getting married. Jen continued to be very helpful and quickly returned all of my calls. Long story short- I moved back to NY and filed for the removal of condition on my GC alone with Jen's help. Both her and Jim felt confident in the likelihood of a positive with my case and provided me with some peace of mind. It has been a long and trying year but I am happy to say the petition for removal of conditions on my green card was approved a week ago, big thanks to Jen! She will be the first person I will turn to for legal advice in the future. I highly recommend her to anyone in need of legal help. Not only is she highly efficient, meticulous and an experienced professional, but also a compassionate person.

A family member got into a difficult situation and Jen was able to help us get through it whole. She was a very clear and strong communicator and an excellent judge of character. Everyone involved in the process came out stronger for it when the case was done. I recommend Jen Mazzei 100%.

Best Immigration Attorney
I met Jim and Jennifer back in Dec 2015 and explained my situation as I was going through divorce and was in Conditional GC and Jennifer clearly walked me through the process. She is very meticulous and detailed orientated when it comes to any case she takes up. I had a lot to deal with my ex and there was a false allegation against me and I hired Jennifer as my attorney to defend the case and came out clean and the case was dismissed and expunged. I must say Jennifer has been the savior of my life. There were times when I have to quickly reach out to her and she will promptly respond back very soon - I have never ever seen this quality and promptness in any of the attorneys whom I have hired before. Some of the greatest qualities she posses are: * Systematic and very detailed oriented * Prompt & Quick response to your questions. With her help, my conditional residency has been removed and I am now a Permanent Resident of the United States. Thank you so much Jennifer. You are one of the greatest personalities I have ever met in my life.

Short Notice Super Service
I was stuck with a bad lawyer just a week from my trial who I couldn't get in contact with and didn't show up to my week advance appointments. I can't be more thankful for having found Jennifer she helped make the process so easy with detailed information rather than leave me wondering what's going to happen and was honestly just a delight to work with. Always very responsive and on top of her stuff. 10/10

OUTSTANDING ATTORNEY
There are not enough words to describe how amazing Jennifer is. When a family member got into a very difficult situation, she was beyond dedicated, caring and compassionate. Not only did she work hard to help during the time we needed her, she helped come up with a plan to help my family member for years to come. She even follows up often to make sure they are on the right track. Jennifer is an outstanding attorney and person.

I highly recommend Jen Mazzie
The first time I met with Jen she explained all of my options very thoroughly and gave me her recommendation as to which was best for me. From the first meeting to the last court appearance she was always on time and always professional and knowledgeable. She also answered calls or texts from me after hours and on her personal days. I never waited more than a few minutes for a response. She got a d felony knocked down to a violation and really made a bad situation for me and my family turn out as best as it could. I honestly cannot say enough good things about what a terrific lawyer and a great person she is

Couldn't have asked for a better Immigration Lawyer
In March 2016, my wife (now) and I got engaged and we went to Jennifer's office to request help to adjust my wife's status. Back then, she had a student visa. We scheduled an appointment with Jennifer and she explained all the possible option on how to adjust her status so she is legal in the USA. Jennifer was extremely helpful, very responsive and professional. In November 2016, my wife and i got officially married and we immediately filed for her green card. Jennifer helped us gather all the appropriate paperwork and guided us through the entire process. The USCIS received out application at the end of December. Our interview got waived, something that we didn't expect. In March 2017, i received an approval notice for both my work authorization and green card. A week later, i received both by mail. Jennifer was always there in every step of the way. Our experience with Jennifer couldn't be better! She is not just a lawyer; Jennifer is a lawyer who puts her clients first. My wife and i are so happy with our case's outcome and timing. We highly recommend Jennifer for an immigration lawyer. Thank you Jennifer for all your help and support! Our case has gone above and beyond what we ever expected!

Jenny Mazzei, i don't even know where to begin. I will preface this review with one comment. YOU HAVE TO, AT THE VERY LEAST CALL HER AND MEET HER FOR A CONSULT.

Fantastic Attorney!
My wife and I hired Mazzei & Polk to file an immigration petition. Ms. Mazzei was very professional and down to earth. She was informative, direct and easy to reach. She responded quickly to emails and calls and answered every question we had. Her experience with immigration made the process extremely easy for us. With her guidance, our petition was approved in under 10 months. We've recommended her to our family and friends and would do so to anyone needing a hands on lawyer who cares about her clients.
