Lawmakers are debating whether Colorado illegal immigrants who graduate from state high schools should qualify for college tuition that’s lower than the out-of-state amount.

A Senate committee led by Democrats will hear the proposal Thursday and decide whether it should move forward. The Democratic bill would a separate tuition category that is a bit higher that in-state tuition but lower than out-of-state tuition. Illegal immigrant students would qualify if they sign an affidavit saying they are seeking legal status and they graduated from a state school after attending for at least three years.

The bill gives colleges the ability to opt-out of creating the separate tuition category. Senate Bill 15 is expected to have a hard time in the Republican-controlled House if it reaches there.
