It is important to clarify that, within the scope of the EB‑3 visa for the United States, there are three subcategories that cater to different professional profiles. Although the terms E31, E32, and EW3 may appear in some documents or discussions within the immigration field, they are used to practically differentiate the three groups of professionals who fit into the EB‑3 category. Each corresponds to distinct requirements and qualifications.

In summary:

• E31 generally refers to professionals who hold a bachelor’s degree and therefore fit as “professionals” under the EB‑3 classification. These cases require the applicant to have a university degree and educational qualifications related to the job offer.

• E32 designates skilled workers – those who do not necessarily possess a university degree but need to prove, for example, at least two years of experience or training in the corresponding field. This category is aimed at people who have trained through practical experience in their profession and can demonstrate technical knowledge or skills acquired over a reasonable period of work.

• EW3 is used to identify “unskilled workers,” meaning those in positions that do not demand extensive experience or training (usually less than two years). These jobs typically refer to operational or support roles which, although essential, do not require the same level of qualification demanded in the other categories.

Each of these designations takes into account the specificities of the position, as well as the education and experience requirements that the employer in the United States must prove to obtain certification from the U.S. Department of Labor and to support the EB‑3 visa petition.

Remembering that immigration is an area with rules and interpretations subject to constant updates, it is always essential that interested parties consult official sources or seek guidance from specialized professionals – avoiding scams or promises of guaranteed results. Strictly following the laws and regulations is essential for a safe and proper process.

I hope this explanation helps you better understand the distinctions between the categories and highlights the importance of seeking reliable information in your immigration process to the United States.
