According to Chambers, Klasko Immigration Law Partners “assembles a dedicated team to tailor institution-specific strategies,” helping clients “prioritize matters effectively and proactively anticipate rapidly evolving immigration policy changes.”

Reinforcing the firm’s longstanding leadership in Pennsylvania, Klasko Immigration Law Partners once again earned the state’s highest ranking, Band 1.

The firm also celebrates the Band 2 debut ranking of Michele Madera, co-chair of the Corporate Immigration Practice, in Pennsylvania. Chambers recognized Michele for her work advising higher education institutions and private employers on a broad range of employment-based immigration matters. One client described her as “an exceptional advisor and partner” who combines “deep expertise, strategic insight and a practical understanding of higher education immigration issues.”
“I’m honored to receive this recognition from Chambers,” said Michele. “Helping our clients navigate immigration challenges while advancing their organizational goals is tremendously rewarding, and this recognition reflects the collaborative work of our entire team.”
