Hi surlefil, greetings from a fellow South American. I agree with the recommendations listed above. I would add Columbia. Although it is not a "Continental Program", it has Lydia Goehr (Aesthetics and Critical Theory), Axel Honneth (current director of the Frankfurt School, he is at Columbia half of the year), and Frederick Neuhouser (expert in Hegel). There are other faculty in political philosophy, but not from a continental perspective. Another good school for you would be SUNY Binghamton, whose whole program is geared towards Ethics and Political Philosophy. My advisor personally knows the chair of the department, Max Pensky, and she thinks he's s among the best scholars in Critical Theory.
Suerte,
