This simply could not be true if without the professional help from the North America Immigration Law Group. I don't think that my background conditions were safe for this application. But I knew that their preparation strategy made my case pretty strong. Although the application was long and challenging, it was very nice to work with their team during the whole process period. They impressed me with excellence, professionalism, and highly responsiveness. I do believe that their service is the best one in the immigration business.
