The Kino Border Initiative reported on recent cases of expulsions into Mexico of particularly vulnerable migrants who do not speak Spanish:
Sixteen percent of those arriving at KBI in the last two weeks of December originally migrated from Haiti. Several of the Haitian families could not respond to simple questions in Spanish without the assistance of an interpreter. In some cases, one individual from the group spoke enough Spanish to interpret for others who did not speak Spanish. One young Haitian woman described experiencing discrimination during their journey north. She reported that her family was extorted in every country they traveled through, including members of the Mexican National Guard who stopped them in southern Mexico, opened up their backpacks, and took whatever they wanted.
Numerous indigenous families from Guatemala have been expelled to Nogales under Title 42, putting them at particular risk of discrimination in Mexico due to language barriers and cultural differences. A Guatemalan family whose primary language is Mam was expelled last week after attempting to cross into the US to seek asylum, as was a Guatemalan man whose primary language is Cakchiquel.
