American empire generated a variety of new migration streams and immigration issues, however, for U.S. officials. While increasing numbers of Puerto Ricans and Filipinos set their sights on the mainland United States, colonial officials worried about Chinese migration into the Philippines and the invasion of Puerto Rico by neighboring island residents. Thus not only did U.S. officials seek to regulate the migrations of their newly-acquired colonial subjects, they also redefined the distant borders of entry and exit for those “birds of prey,” as one U.S. immigration official called them in 1900, who sought to use the territories as a stepping-stone to the mainland United States. The expansion of U.S. territorial control thus also demanded, according to colonial officials, the expansion of the U.S.’ increasingly restrictive immigration regulation apparatus.
The paper thus provides a deeper understanding of transnational migration and law in the era of American empire. It begins to show how the laws of immigration were deeply entwined with the laws of empire – both serving as regimes of inclusion and exclusion, of expansion and contraction that ultimately sought to pull the territories into the U.S.’ jurisdictional orbit.
