In every situation there are two-sides to the story. Here is one side, the Citizens For Immigration Reform (CFIR). 
CFIR is a grass-roots organization formed by citizens who are concerned over the impact of illegal immigration on the United States. They are a non-partisan organization who “call for our borders to be secured by quickly providing for more border patrol agents, erecting a fence, employing technology, upgrading the electronic employer verification system and enforcing employer sanctions. For the abolishing of all non-emergency benefits to illegal aliens, particularly bestowing citizenship upon children born of illegals in the U.S.”
From this site you can learn why Americans have opposing views on immigration. The site contains reasons why illegal immigration hurts the USA. As well as the existing legislative bills that aim to restrict the leniency the USA has over illegal immigrants in our country.
If the CFIR is too conservative for you- the Americans For Legal Immigration (ALIPAC) is more news oriented and less opinion based.
