This data is from a reputable organization and is well worth reading. Most of us, including Republicans, support a compassionate approach to those who've been here for years, favoring allowing them to stay provided conditions are met rather than deportation.
Also worth remembering is that illegal immigration is not a growing problem. Overall numbers have leveled off, and the median time spent in this country has increased from approximately eight to a dozen years. Millions of illegals have been here for years, working hard, raising families and contributing to their communities.
