Immigration lawyers and consultants work closely with clients to ensure that all necessary documentation is filed correctly and on time, and that clients are informed of their legal rights and obligations throughout the process. The industry is heavily regulated by government agencies, and companies must stay up-to-date on changes to immigration laws and policies in order to provide effective services to their clients.
