What was the significance of the U.S. v. Heller case in relation to immigration?

The U.S. v. Heller case, decided by the Supreme Court in 2008, was significant primarily because it affirmed an individual's right to possess a firearm for self-defense within the home, which has implications for various groups, including immigrants. The ruling emphasized the Second Amendment's protection of personal self-defense rights, thereby highlighting the broader theme of individual rights in American society.

For immigrants, this case is particularly relevant as it underscored the notion that they, like all residents, have the right to defend themselves. This has important ramifications for understanding how legal protections are extended to immigrants in the context of self-defense and personal safety, especially in areas where they may face discrimination or crime.

While the other options touch on relevant issues, they do not accurately reflect the core implications of the Heller decision in relation to immigration. The case did not specifically address immigration quotas, business rights, or impose bans on certain countries, which are separate topics in immigration policy discussions.
