The EB-3 visa is a preference category within the employment-based immigration system in the United States. It is designed for skilled workers, professionals, and other workers who are seeking permanent residency in the U.S. Here are the benefits and general procedures for the EB-3 visa:

Benefits:
Permanent Residency: The primary benefit of the EB-3 visa is that it leads to lawful permanent residency (green card) in the United States.
Employment Authorization: Once the EB-3 visa is approved, individuals can work and live permanently in the U.S. for any employer.
Dependents’ Eligibility: Spouses and unmarried children under 21 years old of EB-3 visa holders are eligible to accompany or join the principal applicant as derivative beneficiaries.

Procedure:
The EB-3 visa is divided into three subcategories:

EB-3A – Skilled Workers:
Eligibility:
Individuals with at least two years of job experience or training.
Procedure:
1) The employer must obtain a labour certification from the U.S. Department of Labour (DOL).
2) Once the labour certification is approved, the employer files Form I-140, Immigrant Petition for Alien Worker, on behalf of the employee.
3) If the Form I-140 is approved, the employee can apply for an immigrant visa or adjustment of status.

EB-3B – Professionals:
Eligibility:
Individuals with a U.S. bachelor’s degree or foreign equivalent.
Procedure:
1) Similar to EB-3A, the employer must obtain a labour certification.
2) After approval, the employer files Form I-140 for the employee.
3) If the Form I-140 is approved, the employee can apply for an immigrant visa or adjustment of status.

EB-3C – Unskilled Workers (Other Workers):
Eligibility:
Individuals performing unskilled labour requiring less than two years of training or experience.
Procedure:
1) Employer obtains a labour certification.
2) After approval, the employer files Form I-140.
3) If the Form I-140 is approved, the employee can apply for an immigrant visa or adjustment of status.

General Procedure:
Labour Certification:
The employer must obtain a labour certification from the DOL, demonstrating that there are no qualified U.S. workers available for the position.
Form I-140 Filing:
The employer files Form I-140 on behalf of the employee. This form is used to petition for an immigrant worker and establish the qualifying relationship between the employer and the employee.
Approval of Form I-140:
If the Form I-140 is approved, the employee can move forward with the immigrant visa application process.
Immigrant Visa Application or Adjustment of Status:
If the employee is outside the U.S., they can apply for an immigrant visa through a U.S. consulate. If the employee is already in the U.S., they can apply for adjustment of status (Form I-485) to become a permanent resident.
Immigrant Visa Interview:
If applying from abroad, the employee attends an immigrant visa interview at the U.S. consulate.
Green Card Issuance:
If the immigrant visa is approved or adjustment of status is granted, the employee receives a green card, granting them permanent residency.
