The EB3 unskilled visa, also known as the third preference 'other workers' employment-based visa, is not a direct path to US citizenship. While the EB3 visa provides an opportunity to obtain a green card, which grants permanent residency in the US, it does not automatically grant citizenship, but it does put you on the right path towards citizenship.

After obtaining an EB-3 visa (green card) and living in the US as a green card holder, individuals can typically apply for US citizenship after a period of five years. However, the path to citizenship involves meeting certain eligibility requirements, including continuous residence, good moral character, and passing an English and civics test. It's important to note that obtaining an EB-3 visa is a step towards permanent residency, and the process of becoming a US citizen involves additional steps and requirements beyond holding a green card.
