I am very happy with their work since they are very professional and commitment group. indeed, they provided very strong recommendation letters as well as excellent Petition letter for my EB1 application. during our communication they provided the best advice and constructive comment. My EB1 application was approved in 11 Days. Furthermore, two friends of mine received their approval in EB1 category with help of Chen immigration group. I already recommended this group to some of my friends and colleagues. I would like to give a five-star rating to Chen immigration group.
