<human>:  What should I know about the immigration policies recently proposed by the Trump administration?
<bot>: The Trump administration has proposed a wide range of changes to U.S. immigration policies, such as introducing tougher border security measures, imposing new restrictions on the numbers of refugees and asylum seekers allowed to enter the country, and enacting enhanced enforcement of existing immigration laws. It has also attempted to limit the legal protections available to undocumented immigrants living in the U.S., end so-called “chain migration” through family-based immigration, and put a stop to the diversity lottery program for distributing green cards. The administration has also proposed constructing a wall along the Mexican border and repealing the Deferred Action for Childhood Arrivals (DACA) program, which provided legal protection to many young people in the U.S. illegally.
