EB-1B is an immigration category for professors and researchers who are internationally recognized as outstanding in a particular academic field. Application requires at least three years of eligible teaching or research experience and an offer from a qualifying U.S. employer. Unlike EB-1A, an individual cannot file an EB-1B petition on his or her own behalf without the employer present. 1
In this category, two separate dossier grounds must be established together: the qualifications of the researcher or faculty member and the suitability of the proposed position with the employer. It is not right for a person with strong publications to apply with an unsuitable job offer, or for every employee of a good university to be automatically deemed suitable. 1
Who can be considered for EB-1B?
People teaching or researching at the university, as well as people working in research units of private employers who meet the appropriate conditions, may be considered. The professional title of "professor" alone is not sufficient or mandatory in every file. The research or teaching nature of the work in a particular academic field and the international recognition of the person are important. 1
Just working on an innovative product in a private company file may not be enough. The employer's research unit, researcher staff and documented academic achievements are examined. General business management or casual product support should not be considered the same as an appropriate research position. 1
How to show international recognition?
There are six types of evidence in the regulation, and evidence is normally presented on at least two of them. These include major awards or honors, memberships that require extraordinary achievement, publications written by others about the person and his work, evaluation of the work of others, original scientific or academic research contributions, and authorship in internationally circulated academic publications. 1
This evidence should not be viewed merely as a numerical list. The nature of a publication, the context of the contribution, independent recognition, and the individual's level in the field should all be described together. The employer's research budget and the person's academic recognition are different factors; Evidence for each must be established separately. 1
What records describe three years of experience?
Experience must be based on teaching or research in the relevant academic field. Employer letters should set out the content and dates of duties. It should not be assumed that each year of the PhD will automatically count. If the degree has been completed, teaching undertaken with full course responsibility or doctoral research deemed outstanding in the field may be considered under certain circumstances. 1
Therefore, it is not enough to simply calculate the period between the diploma date and the first job date. The nature of the work, its full-time nature, the level of responsibility and the legal condition on which the experience is based should be explained. If a role involves both teaching and research, an employer letter can clearly illustrate this distinction. 1
What should a suitable job offer look like?
A tenure-track or tenure-track teaching position or a permanent research position at a university or higher education institution may be considered. For private employers, a permanent research position, the competence of the relevant research unit and additional employer conditions in the regulation are required. Not every temporary postdoc or temporary contract is automatically eligible. 1
The term “permanent” does not mean that the worker cannot be laid off at all. The indefinite or indefinite nature of the offer and the continuity of the work are evaluated within the context of the contract and the institution's implementation as a whole. Project financing, contract duration and renewal structure should be examined from the beginning. 1
Application and Green Card phase
US employer submits I-140 petition. PERM labor certification is not required for EB-1B. The employer's capacity to pay the offered wage is also documented from the appropriate period. After approval, the I-485 or consular process is completed according to the visa number and the person's conditions. 123
Within the scope of premium processing, there is a processing time of 15 business days for EB-1B I-140. This is not a deadline for final approval or completion of permanent residence. Current employment status must also be maintained while the application is pending; I-140 approval should not be considered as a sole authority to work. 45
What should be prepared for the first evaluation?
A current academic curriculum vitae, publication and citation records, referee documentation, description of significant contributions, and letters indicating past assignments are useful. For the employer, records should be prepared regarding the nature of the offer, the structure of the department or research unit, and, if a private employer, additional researcher conditions. 1
In the evaluation to be made with Clinch Law Firm, the legal structure of the offer as well as the strong profile of the candidate should be examined. If EB-1B is not appropriate, EB-1A, NIW, or temporary work options may be addressed through separate standards; One does not automatically replace the other. 167
