President Bush himself has not officially proposed an immigration act.  The House of Representatives passed an immigration act, which they may have discussed with President Bush, and the act is now being debated by the senate.  The senate must pass the house act in order for it to become a law.\nPresident Bush, of course, has official positions on immigration, which he has discussed in several speeches.  Bush's proposal has three basic aspects: (1) securing the border, (2) strengthening enforcement inside the country, and (3) creating a temporary worker program.  \nThe details of Bush's proposal can be found on this fact sheet from the White House:  http://www.whitehouse.gov/news/releases/2006/03/20060327-1.html
