The term '''"Sanctuary City"''' is a city or state that enacts policies which are favorable to illegal immigrants. Specifically, sanctuary cities often mandate local laws which prevent inquiry into a person's immigration status, unless they are a suspect of crime or have been deported in the past. <Ref> http://www.humanevents.com/article.php?id=20547&c=1&tb=1&pb=1&gd=05042007</ref>

Often, however, sanctuary cities lack clearly written laws harboring illegal aliens. Instead, they can be identified by their treatment of illegal aliens.
