Ph.D Student It has been a nice experience to work with the North America Immigration Law Group. They used their knowledge, experience, and skills to select key information from my “summary of contribution”. My attorney integrated these pieces of information and drafted my petition. My attorney, also, did a great job to highlight my findings in the recommendation letters with a technical language. All my recommenders signed the recommendation letters with almost no change. They have a broad knowledge and experience and they answered my question in a reasonable time. The result of their work was approved in less than 6 months without RFE. I am happy to work with them and strongly recommend Chen’s group to my colleague and friends.
