PHOENIX, Arizona (Reuters) -- President Bush's pledge to push for an immigration overhaul in an address to Congress on Tuesday, met a mixed response from Hispanics who said it was broadly positive but lacked details.

In his annual State of the Union address, Bush urged lawmakers to support "comprehensive immigration reform" that included a temporary guest-worker program and beefed up security on the porous Mexico border.

The National Council of La Raza said renewed interest on immigration from Bush, together with a shift to Democratic control of Congress, has created the conditions to move forward on the issue.

But not all Hispanics were encouraged by the president's remarks. The League of United Latin American Citizens said Bush's speech contained nothing new about immigration policy in general, and was unclear about the status of 10-12 million illegal immigrants living in the shadows in the United States.
