A bill in the Iowa House would require students to prove they are U-S citizens or are “lawfully present” in the U-S in order to quality for in-state tuition at the state’s public universities and community colleges. Hector Salamanca Arroyo, of Waterloo, says he qualified for in-state tuition to attend DMACC in 2011 before he received deferred-action status under DACA. He told a House subcommittee Monday that without in-state tuition, college would have been unaffordable.
