The administration of American President Donald Trump is changing rules for migrants seeking asylum at the southern U.S. border. The new rules say that migrants must seek asylum in the country they pass through to get to the southern U.S. border before they can seek asylum in the United States. Asylum is political protection given by one country to a person who is from another country. Usually people who seek asylum fear they would face danger if they return to their own country. The new rules offer “limited exceptions.” These include if a person has been trafficked, if they passed through a country that has not signed major international migration treaties or if they have been denied asylum in the third country. The rule is set to go into effect Tuesday.
