Pennsylvania elected officials and local advocates signed on to an amicus brief in support President Obama’s executive actions on immigration.

The brief urges the U.S. Supreme Court to reverse a lower court's ruling that effectively halted Obama's actions last year. On Tuesday the U.S. Conference of Mayors added their support to a growing list of almost 120 cities and counties.

Among the Pennsylvania officials who have signed on to amicus brief are:

William Peduto, Mayor of Pittsburgh; Elizabeth A. Goreham, Mayor of State College; Matt Cartwright, U.S. Representative; Brendan F. Boyle, U.S. Representative; Michael F. Doyle, U.S. Representative; Chaka Fattah, U.S. Representative; Charles H. Ramsey, former Philadelphia Police Department Commissioner; Pennsylvania Immigration and Citizenship Coalition; South Asian Bar Association of North America; and International Service Center, Michael A. Nutter, former mayor of Philadelphia.

According to an analysis by the Center for American Progress on the economic impact of both executive actions, “51,000 of Pennsylvania residents are eligible for DAPA and expanded DACA and implementation of the programs would result in $17,695,000 increase in state and local tax revenues.”

The DAPA and expanded DACA programs will allow eligible immigrants who are parents of U.S. citizens or legal permanent residents, or have lived here since they themselves were children, to apply for deferral of deportation after registering with the government and clearing criminal background checks, putting them on the road to paying even more taxes.

The Supreme Court is scheduled to hear the case April 18.
