Before DACA was announced, our Office was consulted about whether such a program would be legally permissible. As we orally advised, our preliminary view was that such a program would be permissible, provided that immigration officials retained discretion to evaluate each application on an individualized basis. We noted that immigration officials typically consider factors such as having been brought to the United States as a child in exercising their discretion to grant deferred action in individual cases. We explained, however, that extending deferred action to individuals who satisfied these and other specified criteria on a class-wide basis would raise distinct questions not implicated by ad hoc grants of deferred action. We advised that it was critical that, like past policies that made deferred action available to certain classes of aliens, the DACA program require immigration officials to evaluate each application for deferred action on a case-by-case basis, rather than granting deferred action automatically to all applicants who satisfied the threshold eligibility criteria.
