Some of the recent changes to U.S. immigration policy as of 2015 include protection for several groups of undocumented immigrants as well as expanded programs for foreign students and investors, according to the Washington Post. However, many states have issued legal challenges, causing delays in these programs.
In 2012, President Obama signed an executive order offering three-year work permits to millions of "Dreamers," or immigrants who were brought illegally to the United States as children, notes the Pew Research group. The administration implemented an expansion of this program as well as a similar program for parents of U.S. citizens or legal residents in 2014, according to the Washington Post. However, a federal court order suspended these changes after a lawsuit by 26 states, including Texas and Florida. The U.S. Citizenship and Immigration Services website lists the current status of these programs and the more restrictive guidelines for the Deferred Action for Childhood Arrivals program, which limit applicants to those who were born after 1980 and have been living in the United States since 2007.
