"Roma," which won the Golden Lion at the Venice Film Festival, is a deeply personal film for the director of "Gravity" and "Children of Men." It is Cuaron's first in Spanish and first filmed in his native country since his 2001 breakthrough "Y Tu Mama Tambien."
Mexico has competed for the trophy eight times, most recently in 2011 with "Biutiful" by Alejandro G. Inarritu, but has never won.
"Roma," with Oscar-winner Cuaron also serving as cinematographer, will be available on Netflix this December.
Academy Award nominations will be announced on Jan. 22.
