TUCSON, Ariz. (AP)—President Bush is trying to build support for a comprehensive immigration strategy — and mollify conservatives wary of his guest worker plan for foreigners — even though Congress has largely shelved the issue for now.

The president's plan pairs a guest worker program for foreigners with border security enforcement, an attempt to satisfy both his business supporters, who believe foreign workers help the economy, and his conservative backers, who take a hard line on illegal immigration.

In Tucson, the president planned to aim remarks in a speech at those conservatives, emphasizing his proposals to secure the border, remove people who enter the country illegally and strengthen enforcement of immigration laws.
