WASHINGTON (Reuters) - A bipartisan group of U.S. Senators has agreed on a framework for immigration reform that would provide a "path to citizenship" for those in the United States illegally but only after measures are put in place to secure borders and track undocumented immigrants.

The document, made available to news organizations early Monday and first reported by Politico, comes a day before President Barack Obama is to outline his proposals for immigration reform.

An outline of the proposal said it would allow those in the United States illegally to register with the government, pay a fine, and then be given probationary legal status allowing them to work.
