What does the Immigration and Nationality Act regulate?

The Immigration and Nationality Act (INA) is a comprehensive piece of legislation that governs immigration and nationality law in the United States. It regulates various aspects related to the employment of non-citizens, including the conditions under which aliens can be employed temporarily or permanently. This includes the requirements that employers must meet to hire foreign workers, the processes for different visa categories, and the legal rights of employees who are not U.S. citizens.

The INA outlines the criteria for various employment-based visas, ensuring that both employers and foreign workers adhere to specific legal guidelines. This regulatory framework helps to manage and oversee the flow of skilled and unskilled labor into the U.S. economy.

In contrast, the other options do not accurately represent the scope of the INA. While concerns such as permanent residence, health insurance, and tax obligations may be related to the broader topic of immigration, they fall under different legal frameworks or acts. The INA focuses specifically on employment conditions among other immigration-related matters.
