This is a resolution expressing what the House of Representatives believes should happen regarding military enlistment rules. Specifically, it's asking the Secretary of Defense to review and potentially change current rules that affect certain immigrants who want to join the U.S. Armed Forces. The resolution focuses on people who have DACA status—that's the Deferred Action for Childhood Arrivals program, which provides work permits to immigrants who came to the U.S. as children. Currently, federal law has restrictions on enlisting non-citizens, but this resolution is asking the Defense Department to look at whether they can make an exception for DACA recipients who have valid work authorization documents. It's important to note that this is just a resolution expressing the House's opinion—it's not a law that changes anything by itself. It's essentially a formal request asking the Pentagon to review the rules and consider whether DACA recipients should be allowed to serve in the military.

Expressing the sense of the House of Representatives that the Secretary of Defense should review section 504 of title 10, United States Code, for purposes related to enlisting certain aliens in the Armed Forces.
