WASHINGTON (AP) - Likelihood is dimming that Congress will pass an overhaul of the nation's immigration system. So President Barack Obama is relying more and more on minor changes to the law.
    
As a candidate, Obama promised to pass immigration reforms. And his initial changes were broad and controversial.
    
Obama instructed the government to use its discretion to find and deport only the most serious criminals. And in mid-2012, he announced a plan to offer young immigrants in the country illegally a reprieve from deportation and work permits for at least two years.
    
But the White House has shifted lately. Now it's chipping at the edges with relatively minor procedural changes. For example, the administration has also allowed immigrant spouses and children of citizens to stay in the U.S. in some cases.
