Roughly 1,000 to 1,200 people set out before dawn from Tapachula bound for Mexico City to press for residency papers and access to work. Cubans make up the majority of the group, with others from Honduras, Ecuador, Brazil, Haiti and additional Latin American countries reported. Participants describe months-long delays at Mexico’s COMAR office and allege pay-to-expedite schemes costing up to 20,000 pesos. Migrants say scams, theft of documents and unaffordable living costs in southern Mexico pushed them to leave the border city. The group organized informally over social media and emphasizes staying in Mexico, a strategy reshaped after President Trump ended the CBP One appointment program.
