We used : Law offices of Michael Boyle at Connecticut, while working in Chicago... Very thorough lawyer and sincere. Our whole process from Labor to GC took about 7 months with no questions asked in EB2. No request for more information from INS...not a single hiccup. He had everything ready and the funny part is we never even met in person...all was done over the phone and postal mails (He had done similar work for my work place before and that is why he was recommended to us).
