It has been a great pleasure working with North America Immigration Law Group on my I-140 petition case. Every my questions were responded promptly as they promised. The documents were also well prepared even for their first drafts and only several minor items needed to be revised. Throughout the whole preparation procedure, I am highly impressive by their carefulness to double check all the documents to make sure they were correctly prepared before filling. The team are professional. They know exactly what to exhibit/to avoid to strengthen the case. I appreciate all their great works and highly recommend their services.
