Both domestic and international companies invest heavily in their most valuable resources: their employees. Lawyers in Armstrong Teasdale’s Immigration practice area protect this investment by securing temporary visas, permanent residence and U.S. citizenship for our clients’ foreign employees without disrupting their businesses.

Our team has extensive experience assisting corporate clients in obtaining permanent residence status for their employees. In the U.S., we do this by obtaining labor certification or petitioning the U.S. Citizenship and Immigration Services (USCIS) to classify individuals as either outstanding researchers, individuals with extraordinary ability or as multinational executives or managers.

Our team also has experience in securing a variety of visas including:

  • E-1 / E-2 – Treaty Traders and Investors
  • H-1B / H-3 – Professionals / Trainees
  • L-1A / L-1B – Intracompany Transfer
  • O-1 – Extraordinary Ability
  • TN – North American Free Trade Agreement (Canadian or Mexican)

We also represent corporate clients on workplace compliance issues, including I-9 issues, as well as audits conducted by the Department of Labor or the Department of Homeland Security. The Immigration practice area also assists corporate clients involved in mergers and acquisitions to ensure that the foreign employees involved in a corporate reorganization maintain their immigration status.

In addition, our immigration lawyers provide services to individuals on a variety of issues, including obtaining permanent residence status through marriage to a U.S. citizen or a lawful permanent resident. We also assist individuals in obtaining business visas, fiancé visas, travel documents, work authorization documents, and naturalization and citizenship processing.

We work with local counsel around the world to help corporate clients seeking to transfer abroad employees to countries outside the U.S. by securing appropriate work and travel documents.

Our immigration team and other Armstrong Teasdale professionals provide bilingual services in German, Portuguese, Spanish, Japanese, Mandarin, Cantonese and French.
