With more than a decade of immigration law experience, Regina Knoll represents a diverse group of people and business entities, including U.S. and foreign companies spanning across all sizes and industries, foreign investors, professionals, people of extraordinary ability in the arts, sciences, business, and education, religious workers, performers and athletes, family members of U.S. citizens, victims of violence (including domestic violence), and asylum seekers. Ms. Knoll also assists with immigration matters pertaining to visits to the United States for business and pleasure, temporary and permanent employment, and study and exchange in the United States.

Before joining Higgs Fletcher and Mack, Ms. Knoll founded and served as the principal attorney at the Law And Effect Group, a San Diego-based immigration law firm. Previously, she worked as in-house counsel at DiscounTechnology, where she handled a variety of transactional matters in such areas as intellectual property law, contract law, employment law, and immigration law. Originally from Austria and a native German speaker, Ms. Knoll is one of the preeminent immigration attorneys for German companies with subsidiaries in Southern California and beyond.

Her work includes:

Employment-Based Immigration

  • Employer-sponsored immigrant petitions and adjustment of status (“green card”) applications, including Labor Certification Applications with the Department of Labor;
  • Petitions by foreign nationals with extraordinary abilities in the sciences, arts, education, business, or athletics;
  • Petitions on behalf of outstanding professors and researchers, multinational managers and executives, and foreign nationals with advanced degrees;
  • National Interest Waiver petitions;
  • Employer-sponsored non-immigrant visa petition (temporary work visas), including visas for professionals, intra-company transferees, performers, artists, athletes, and religious workers;

Immigration Matters concerning the LGBTQ Community

Ms. Knoll is affiliated with several LGBTQ-oriented organizations and enjoys a strong connection with the LGBTQ community. In June 2013, with the fall of the Defense of Marriage Act, the full array of immigration benefits and legal remedies finally opened up to gay and lesbian individuals and same-sex couples. Ms. Knoll was among the few immigration attorneys to represent a same-sex couple on the first day that such marriage-based petitions were heard by the U.S. Citizenship and Immigration Services in San Diego. Since then, she has been tirelessly representing the immigration rights of gay and lesbian foreign nationals and same-sex couples.

Ms. Knoll also handles immigration cases involving Naturalization and Citizenship, Diversity Visas (“visa lottery”), petitions under the Violence Against Women Act, and Affirmative Asylum applications. In her work, Ms. Knoll routinely interacts with officers and agents of U.S. Citizenship & Immigration Services, U.S. Customs & Border Protection, U.S. Immigration & Customs Enforcement, Department of Labor, Department of State, and State and local government agencies.

Ms. Knoll understands the importance of making the legal process as understandable and accessible as possible to her clients. She is well-versed in serving the complex needs of corporate clients of all sizes and backgrounds and in paying personalized attention to the immigration needs of individual clients.
