Administrative Relief is a program President Obama has enacted to protect certain groups of immigrants from unfair deportation, and give some of them access to work permits. 

It is an expansion of a program that has been around for a long time, called Deferred Action.   

A grant of deferred action under this program is temporary – it is only good for 3 years.  After that, you may be able to renew.  It is not a pathway to getting a green card or U.S. citizenship.
