The correct answer to this open question is the following.
Many special interest groups would likely to challenge recent immigration laws in Arizona and support legislative acts such as the DREAM (Development, Relief, and Education of Alien Minors) Act. For instance, the Catholic Charities Community Services of Phonix, also known as "Familias Unidas," in Phoenix, or Arizona Legal Women and Youth Services, also in Phoenix.
These interest groups have played an important role since DACA legislation tried to be rescinding by the present administration. DACA or the Deferred Action for Childhood Arrivals, protect the young undocumented immigrants. That is why many interest groups have exerted pressure on Congressmen to pass the Dream Act.
