Personal Background

Roger Tsai is Of Counsel to Holland & Hart with a practice focusing on employment and family-based immigration and worksite enforcement. He counsels universities and companies in the healthcare, technology and energy sector on securing temporary and permanent visas for foreign national employees, including H-1B visas and permanent resident status. He also represents companies under investigation by the Bureau of Immigration and Customs Enforcement, and helps companies perform internal audits of their employment eligibility documents.

Mr. Tsai is a strong advocate on immigration issues nationally. As a member of the Board of Governors for AILA, an organization that represents over 10,000 immigration attorneys nationwide and 60 attorneys in Utah, Mr. Tsai testified on landmark state immigration laws before the Utah State Legislature. He has also spoken at national conferences for the Federal Bar Association and the American Immigration Lawyers Association on immigration worksite enforcement. Mr. Tsai's articles on immigration have been published by the American Bar Association and the American Immigration Lawyers Association. He was the first non-Hispanic member of Governor Herbert's Hispanic Advisory Council, and was instrumental in finding common ground on the divisive issue of immigration through dialogue between state lawmakers and the Hispanic community.

Firm Background
