If they are not enforced, why should we have any laws at all? Federal immigration laws exist to protect this country's citizens and did NOT create this mess for such illegal immigrants. They and/or their parents put them into this situation. Do not blame our citizens who expect U. S. laws to apply to all equally. How hypocritical is the Mexican government? Its leaders demand that OUR country keep its citizens who came here illegally. However, Mexico's government has armed guards at its southern border to stop citizens from countries south of Mexico from entering Mexico illegally. The Mexican military locks such people into trains, ships them north to the U. S. border, and dumps here. News source: NPR.
