Family Testimonials of Our Services

“John Nahajzer worked with me for 10 years on various aspects of my work and immigration into the US. We successfully obtained an L1A visa and associated renewals, and subsequently a Green Card. John was excellent throughout, as was his team of paralegals. Having had some experience with other lawyers, I cannot rate John highly enough!”


“This … conveys the happy news that my husband’s case has been resolved and… that he has become a Permanent Resident of the United States. We know that our case would not have reached a successful conclusion without the assistance of … everyone at Maggio-Kattar…. Please accept our many thanks for all your hard work on our case and be assured that we will recommend you and your firm in the future.”

“I really want to share my unique experience with attorney James Alexander who is leading attorney from Maggio Kattar with high quality professionalism. My family is so fortunate to have James Alexander as our attorney and that is definitely the best decision I ever made. Our case is somehow vague with certain immigration regulation thus require an very experienced immigration attorney with in-depth specialized immigration legal knowledge and strong ability to persuade. …I would definitely recommend James Alexander from Maggio Kattar to any one who are in need of an unique, highly specialized and very responsible attorney to fix their immigration issues.”
