Donald Trump has expanded the travel ban to include five additional countries, bringing the total to 17 nations facing full or partial restrictions on entry to the United States. The move follows a National Guard shooting in Washington, DC, involving an Afghan immigrant, which prompted the administration to intensify border security measures. The White House cited security concerns, including unreliable local records and high visa overstay rates, as reasons for the expanded ban and new visa restrictions affecting fifteen more countries. The decision has sparked criticism from immigration advocates and Democratic lawmakers, who argue that the bans are overly broad and risk separating families. In response to the shooting, the administration has paused Afghan visa processing, ordered retroactive reviews of green cards and asylum cases, and halted benefits for immigrants from nineteen countries.
