Which of the following actions constitutes a violation of 8 USC 1326?

The action that constitutes a violation of 8 USC 1326 is attempting to enter the United States after being deported. This specific section of the U.S. Code makes it illegal for individuals who have been previously removed or deported from the country to re-enter or attempt to re-enter without the permission of the Attorney General. This law is designed to deter repeated illegal entries and emphasizes the importance of maintaining legal immigration processes.

In contrast, entering the U.S. with proper documentation, applying for a visa, or even traveling without legal status do not constitute violations under 8 USC 1326. Entering with proper documentation complies with immigration laws, applying for a visa is a legal process that allows individuals to seek entry, and traveling without legal status, while potentially unlawful in other contexts, does not specifically involve the act of re-entering after deportation, which is the focus of 8 USC 1326.
