crisis, media outlets and state officials have raised concerns about increasing discrimination against migrants in the country, especially xenophobia and violence against the migrants. Guyana There have been racial tension between the Indo-Guyanese people and the Afro-Guyanese. Mexico Racism in Mexico has a long history. Historically, Mexicans with light skin tones had absolute control over dark skinned Amerindians due to the structure of the Spanish colonial caste system. When a Mexican of a darker-skinned tone marries one of a lighter skinned-tone, it is common for them say that they are " 'making the race better' (mejorando la raza)".

Racism against indigenous people has been a current problem in Mexico. Domestic workers, many of whom are indigenous women who have moved from rural villages to cities, often face discrimination including verbal, physical or sexual abuse. Panama Peter Szok argues that when the United States brought in large numbers of laborers from the Caribbean—called "Afro-Panamanians"—to build the Panama Canal (1905–1914), xenophobia emerged. The local elite in Panama felt its culture was threatened: they cried out, "La Patria es el Recuerdo." ("The Homeland is the Memory") and developed a Hispanophile elitist identity through an artistic literary movement known as "Hispanismo." Another result was the election of the "overtly nationalist and anti-imperialist" Arnulfo
