Having been married to a former Eastern European and having gone through the immigration process personally, I can attest to the breadth and depth of immigration knowledge of Attorney Sullivan. He has managed to quickly and efficiently help many of my fellow colleagues deal with their immigration issues. Now, that we have a president, and congress enforcing immigration, law it is crucial to hire someone with 25 plus years of experience in this area, you get one shot at getting it right!

Jason is a professional lawyer. He has a great attitude and is always very supportive. Even when I received an RFE for my EB2-NIW green card application, he remained patient and worked with me to carefully discuss and craft a strong response. My green card application was successfully approved at the end. It was a pleasure working with him！

Thanks to Mr. Sullivan, my marriage-based green card application was approved in less than 5 months. I understand immigrants very well. What is important for us in this process is that we are looking for a lawyer who will make us feel safe, who will answer our questions knowledgeably and clearly, and who will spare time for us. For these features, Mr. Sullivan is the right address for a quality and disciplined lawyer.

We found Jason through his reviews on Google and before we chose him as our lawyer, he took the time to speak to us a couple of time before starting our visa process. He was knowledgeable, very quick communicator via email/phone. He made time for us and we never felt rushed by him. We highly recommend Jason to anyone who needs immigration assistance.
