The Immigration Impact Lab is CAIR Coalition’s first concerted appellate impact litigation project.

fffLab in depth 2fgg

Every day, we at CAIR Coalition witness the injustices that the detained immigrant men, women, and children we serve increasingly face in the American immigration detention and deportation system.

Through impact cases in our Lab, we respond proactively to these injustices via appeals on issues that have the potential to improve the law for broad groups of immigrants.


In collaboration with our pro bono partners, we experiment with cutting-edge impact litigation in courts throughout the Fourth Circuit, including Maryland, Virginia, and the Carolinas.

With the Lab, we develop novel litigation and leverage limited resources for the maximum impact, presenting a united front to improve the law for all immigrant communities and better protect the due process and liberty rights of immigrants at risk of detention and deportation.

Several cases CAIR Coalition has co-counseled, mentored, or provided amicus curiae support in have helped create precedent that improves the law for broad groups of immigrants, including:
