Mexico and the United States have formed a high-level, joint working group to make immigration safer and more orderly, Mexican officials announced Friday.

The working group will focus on making documented migration easier, protecting migrants' rights and improving procedures for repatriating migrants, the Mexican Foreign Relations Department said in a statement.

It also will focus on steps to inform the public about the dangers of trying to cross the border without documents.

The group was formed through the efforts of Janet Napolitano.
