A more thorough explanation:

BIS

BIS stands for Bureau of Industry and Security. It is a government agency in the United States that is responsible for regulating and enforcing laws related to the export and import of goods that have national security implications.

One example of the BIS's work is reviewing applications for licenses to export certain goods, such as military equipment or technology, to other countries. Another example is investigating and prosecuting individuals or companies that violate export control laws.

For instance, if a company wants to export a piece of technology that could be used for military purposes to another country, they would need to apply for a license from the BIS. The BIS would review the application and determine whether or not to grant the license based on national security concerns.

The BIS plays an important role in protecting national security by regulating the export and import of goods that could be used for military purposes or pose a threat to national security. The examples illustrate how the BIS reviews applications for licenses and investigates violations of export control laws to ensure that these goods do not fall into the wrong hands.
