When hiring an immigration attorney, make sure whether they possess a J.D. degree from an ABA-verified school. They should prove that they have a degree in the legal field. Also, check out the Bar to see if their name is included there. You may also see the rating and reviews left by previous clients. The experience matters as well: it should be no less than five years in the corresponding field. Make sure that the candidate has in-depth knowledge of H, L, E-2, and other types of visas and application documents. They also should have some experience at performing in courts.
