Christopher concentrates much of his practice on the area of employment-based immigration for institutional clients, multinational corporations and universities. His experience includes helping corporations acquire employment-based visas for key

Christopher has significant experience handling matters such as Temporary B-1 (business visitor), E (investors/traders), H-1B (professionals), L-1 (intra-company transferees), O (extraordinary) and TN (NAFTA) visas, permanent labor certification, both traditional and “special handling” for college or university teachers, extraordinary, outstanding researcher/professor and national interest waiver immigrant visa petitions, overseas consular processing of nonimmigrant and immigrant visa petitions, adjustment of status and U.S. citizenship, and counseling on I-9 compliance, Social Security no-match and E-Verify issues.

Prior to joining the firm, Christopher worked as an immigration specialist for a market research firm in the Philadelphia area. He provided training and reference tools to employees, recruiting staff and business managers on visa issues. He assisted in the prescreening process of all foreign national candidates in need of visa sponsorship to ensure their eligibility for hire and coordinated all requirements and necessary paperwork for various U.S. consulates abroad in assisting employees with visa applications. This “client-side” experience gives Christopher a unique perspective in the course of his practice.
