Yale welcomes applicants from all backgrounds. The Admissions Committee seek students with the potential to add to the Yale community and take advantage of the extraordinary opportunities available here. Yale evaluates applications without regard to a student’s citizenship or immigration status, and all students are eligible for Yale’s need-based financial aid. These policies include undocumented students living in the US, whether they hold DACA status or not. Future Yale students will come from public and private schools, from very small towns and great urban centers, and from every corner of the world.
