During the State of the Union, President Trump stated that he wanted to work with both Democrats and Republicans to put together an immigration bill. One of his proposed changes to immigration involves the "Family Reunification Program." This program allows immigrants to apply to have their family members brought to the United States. The President wants to limit this to parents and children. In other words, brothers, sisters and grandparents could no longer legally join family already legally living in the United States.
