Expert Opinion Letters for L-1A, L-1B, or O Visas

EOL for L-1A, L-1B, or O Visas
At Document Evaluation, LLC, we specialize in providing Expert Opinion Letters that address the specific requirements of the U.S. employment-based visa categories such as L-1A, L-1B, and O-1. Each of these visas has well defined purpose and eligibility criteria, so we customized our services to ensure that your case is well-supported with authentic documentation.
When applying for any of these visas, USCIS evaluates whether the petitioner has met the necessary conditions. Based on the supporting documents provided by your legal lawyer, we work with experts to evaluate whether we can give expert opinion letter to support your visa application.
Types of Expert Opinion Letters:
- L-1A (Intracompany Transferee - Executive or Managerial Capacity):
Our Expert Opinion Letter can be used to exhibit that the petitioner holds an executive or managerial role within the company’s organizational structure. The letter will explain how the position meets the criteria for an L-1A visa, highlighting the petitioner’s role in decision-making, leadership, and company operations.
- L-1B (Intracompany Transferee - Specialized Knowledge):
Our Expert Opinion Letter demonstrates that the petitioner possesses specialized knowledge essential to the company’s products, services, or management practices for L-1B visas. The letter outlines how this knowledge is essential to the company’s success and why it cannot be found in the local U.S. workforce.
- O-1 (Individuals with Extraordinary Ability):
Our Expert Opinion Letter supports petitions for O-1 visas for individuals with extraordinary abilities in fields like business, science, education, or the arts. The petitioner’s qualifications are evaluated by an expert in the field, taking into account things like prestigious awards, publications, significant contributions to the field, memberships in prestigious organizations, and other exceptional accomplishments. This analysis is customized to match the O-1 requirements and helps demonstrate the petitioner’s extraordinary ability.
