Happy Client Testimonials

“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.”

“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!”

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.

E.A. - Plaistow NH

In my own attempts to provide information to USCIS to finish the process to obtain Lawful Permanent Resident Status, I received notice that the information I had submitted was inadequate, and without additional documentation, I was in danger of being deported. Mr. Sullivan provided excellent advice, performed research, and assisted in compiling documentation that allowed my application to proceed without further investigation by USCIS. After five long years, I now have my Permanent Resident Status, thanks to the efficiency and hard work of Mr. Sullivan and his staff.
