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. and U.K. 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. In the U.K., we apply for Indefinite Leave to Remain (ILR) or Settled Status for EU nationals from U.K. Visas and Immigration (UKVI).

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)


  • Tier 1 Investor visas
  • Skilled Worker visas
  • Intra Company Transfer (ICT) visas
  • Global Talent visas
  • EU Settlement Scheme and UK Hong Kong BNO visas

We also represent corporate clients on workplace compliance issues, including I-9 issues in the U.S. and Sponsor License issues in the U.K., as well as audits conducted by the Department of Labor or the Department of Homeland Security in the U.S. and the U.K. Home Office (HO). 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. or U.K. 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.

Through Armstrong Teasdale’s membership in the Alliuris network, a group of European law firms specializing in international business law, our team also assists corporate clients on a variety of outbound immigration matters. We work with local counsel around the world to help corporate clients seeking to transfer abroad employees to countries outside the U.S. and U.K. by securing appropriate work and travel documents.

Our experienced U.K. Immigration team, which is recognized as a “leading firm” in the Legal 500 U.K. can provide personalized solutions for all U.K. immigration needs and leverages their contacts at the HO to lobby on behalf of its clients and enable them to resolve issues quickly and effectively. Our lawyers can also provide guidance in navigating the complex U.K. immigration rules given the changing Brexit landscape.

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