Backlog of Pending Cases in Immigration Courts as of July 2013
I cannot copy the graphics from TRACs webpage so you will have to go there to see the nice tables they have created. It is a good site with lots of immigration information so you should check it out anyway. What I can tell you is that the Immigration Court backlog has increased in fairly dramatic fashion coinciding perfectly with the Obama Administration's increase in enforcement and deportations since entering office in 2008.
The backlog of deportation (Removal) cases pending are 2007=174,935; 2008=186,108; 2009=223,809; 2010=262,799; 2011=297,551; 2012=325,044; 2013=342,189
Nativists can decry the prosecutorial discretion advanced by the Obama Admin. in DACA (after the pathetic Congressional fail that was the DREAM Act) but the facts don't leave room for argument. Enforcement is way up under Pres. Obama. Is the huge uptick in enforcement designed to provide political cover for CIR? T-Partiers would certainly think so; but then so what? All those people are just as deported; their families are just as split up as they would have been if Obama's motivations were purely spiteful.
