Visa appointments at the U.S. Embassy in Colombia have been canceled following a dispute between President Donald Trump and his Colombian counterpart Gustavo Petro over deportation flights that nearly turned into a costly trade war between both countries.

When Colombia’s president, Gustavo Petro, refused military planes carrying deportees, infuriating President Trump, he revealed how heated the question of deportations has become.

Trump said the Colombia's refusal jeopardized U.S. national security. He imposed tariffs on incoming goods, sanctions on government officials, enhanced border inspections of Colombian nationals, and banking and financial sanctions.
