The LSA has signed on to a letter which called for support for the Deferred Action for Childhood Arrivals (DACA) program. The letter was also signed by a large number of fellow scientific organizations and associations and was submitted to party leaders in the House and Senate. In it, the LSA jointly asserts that "America is a nation of immigrants. Many DACA participants were brought here when they were very young and have known only the United States as their homeland. This land is their land just as it is ours."

The letter, as well as recent statements and resolutions on other topics can be found in the LSA Resolutions, Statements, Endorsements and Related Actions section.
