A group of immigration agents are challenging the Obama administration’s policy suspending deportations for undocumented residents who came to the United States as children. The lawsuit on behalf of 10 immigration agents was filed in Texas by Kansas Secretary of State Kris Kobach, who helped draft the controversial anti-immigrant laws in Arizona and Alabama and is an informal adviser to Republican candidate Mitt Romney. The lawsuit alleges the Obama administration’s Deferred Action for Childhood Arrivals program prevents agents from detaining immigrants who could threaten public safety. The new program grants temporary legal status to live and work in the country to undocumented people who meet certain conditions, including being under 31 as of June 15, 2012. Tens of thousands of young undocumented immigrants stood in massive lines across the country to apply for deferred action when the policy went into effect last week.
