This forum brings scholars across rhetorical interests together in conversation around the 100-year anniversary of the Immigration Act of 1924. The six essays consider the overt legislation-border regulation-within its historic, ongoing, and contemporary significance. Asking questions that consider borders, migration, and regulation broadly, the authors here move through questions of surveillance, belonging, space, militarization, embodiment, and empire. In doing so, this forum expands the rhetorical project of border rhetorics, naming the expansive reach of borders and border rhetorics.
