Have you worked with The Law Office of Jason M. Sullivan? We would love to hear your feedback! Leave us a review today.

Our journey with Mr. Jason Sullivan began 7 years ago. My husband and I thought our situation was hopeless and irreversible. We lived in fear and suffered many hardships do to our circumstances. Mr. Sullivan, however, had excellent knowledge of immigration law and successfully managed to help us adjust the status of a C1D visa when the time was right. Further, my husband’s case was extremely complex with many obstacles along the way toward an IR1 visa. Due to his hard work and determination, we are currently united as a family and my husband is seeking gainful employment here in the U.S. We will be forever grateful for his dedication to our case. Mr. Sullivan, is an amiable, capable, professional, knowledgeable, and caring individual who takes pride in his work. Highly recommended.

Many lawyers gave up on my case knowing that it was going to take a miracle to win. Attorney Jason Sullivan became the miracle that I needed and I will be forever grateful. Born in Ghana to a poor family, I never imagined I’d have a chance to come to the USA for a better life. Having now been here for 20 years, my mother was worried sick that I would end up deported or in jail. After multiple failed attempts to adjust my status, I was ready to give up myself. Then we found Attorney Jason Sullivan and he took on my case with no hesitation. He knows the law, his work is highly efficient, and he is reliable. It was a long journey but my wife and I are very thankful for Jason and his unwavering dedication to my case.

Jason is very professional, thorough and reassuring. I contacted him with a somewhat difficult situation, one he’d never heard before. I had left his office after my initial meeting feeling confident I was in good hands. Jason was quick to respond to email, personable, knowledgeable, and caring still even after helping me obtain status. I will be forever grateful. Highly recommended!

Trying to navigate though the complicated United States immigration system to get my fiancé to the United States was overwhelming. Attorney Sullivan and his NH Immigration Law Firm made the process easy and painless. I would refer Attorney Sullivan to anyone needing an immigration lawyer.

I worked with Jason on an issue that was time-sensitive. It was in the midst of covid when everything was very slow, and the deadline was approaching. While I was nervous about missing the deadline, he handled the issue with calm, confidence, and integrity and made sure we met the due date. This is to underscore that Jason is very knowledgeable, experienced, and confident in his work. He is the right attorney I would consult in the future if I ever need advice again. I would recommend him to anyone seeking advice on immigration to the States.
