Are you an attorney? Endorse this lawyer

  • Brad E. Bleakney

    I would strongly endorse this lawyer. Dennis Sullivan has expert knowledge available in many of areas of the law but he is the "go to" source for business and private immigration in clearing documented, highly technical, talent and workers for US business needs. Without a doubt.

    I highly endorse Dennis Sullivan in the field of immigration law. Mr. Sullivan is extremely experienced in the field of employment-based immigration typically for multinational corporations. His clients include some of the largest and most well known companies in the Milwaukee area. Working in the employment-based area means PERM labor certifications, immigrant visa petitions, adjustment of status, and a variety of nonimmigrant visas such as H-1Bs, L-1s, TNs, J-1s, and others. Dennis has been recognized as one of the Best Lawyers in America for over 15 years and is AV rated. I consult with him on a regular basis and highly recommend him in this area.
