Donald Trump has a new rule. Some people cannot come to the U.S. from some countries. These countries are Afghanistan, Myanmar, Chad, Congo, Equatorial Guinea, Eritrea, Haiti, Iran, Libya, Somalia, Sudan, and Yemen. It is hard for people from Burundi, Cuba, Laos, Sierra Leone, Togo, Turkmenistan, and Venezuela to get a paper to come. If you do not have the paper, you cannot come. Some people do not like this rule. They say it is not good.
