Established by President Obama in 2012, DACA (Deferred Action for Childhood Arrivals) allowed hundreds of thousands of young undocumented immigrants to live and work legally in the US, subject to renewal every two years. To qualify, you had to be undocumented; have arrived in the U.S. prior to your 16th birthday; have lived continuously in the U.S. since June 15, 2007; be in school or have graduated, obtained a GED, or been honorably discharged from the military; and have no serious criminal record.
There are currently 578,680 active DACA holders throughout the country,
including 4,840 in Massachusetts.
