US immigration categories are something anyone researching this path needs to understand broadly before choosing a specific route. There are many different category groups, each serving a different type of applicant and set of conditions. This article outlines the overall picture to help you determine which path fits you best.

Understanding the full picture helps you avoid confusing the different categories and choose the direction that truly fits your circumstances.

What groups do US immigration categories fall into

Theo U.S. Citizenship and Immigration Services (USCIS), the paths to a green card fall into several major groups: employment-based, family-based, investment-based, and a few special categories.

Each group is based on a different foundation. Employment-based categories are based on work capability and employer sponsorship. Family-based categories are based on family relationships. Investment-based categories are based on capital. Special categories serve specific groups. Understanding this division helps you know which group you fall into.

Employment-based category group

The employment-based group includes preference categories from EB-1 to EB-5, serving everyone from individuals of extraordinary ability to unskilled workers and investors. This group is common for people who do not have a relative to sponsor them in the United States.

Within this group, the third preference category (EB-3) is the most accessible path for unskilled and skilled workers. For most Vietnamese workers without outstanding qualifications or large capital, the employment-based category, especially EB-3, is usually the most practical choice among the groups.

Family-based and investment-based groups

The family-based group is based on a relationship with a US citizen or permanent resident. According to U.S. Department of State, people with an eligible relative may be sponsored, but many categories have long waiting lists.

The investment-based group is based on a significant amount of capital that creates jobs in the United States. This category suits people with substantial financial resources. These two groups serve different applicants than the employment-based group, and not everyone is eligible to participate.

Choosing the right category group

Choosing a category group should be based on your specific circumstances. Those with relatives in the United States may consider the family-based category. Those with substantial capital may consider the investment-based category. Those with a trade and readiness to work usually head toward the employment-based category.

For Vietnamese workers without relatives or substantial capital, the employment-based category, specifically EB-3, is usually the most viable path. What matters is choosing a category that truly reflects your resources and circumstances, rather than chasing a category that sounds appealing but does not fit.

Summary

US immigration categories fall into employment-based, family-based, investment-based, and special groups, each based on a different foundation. For Vietnamese workers without relatives or substantial capital, employment-based categories such as EB-3 are usually the most viable. You should assess your own true circumstances to choose the right path.
