Determining residency status can be difficult for many college applicants, including immigrants and members of the military. The Colorado Dept. of Higher Education now makes it easy to determine whether you should apply for resident or non-resident tuition. Their handy Higher Education Residency Guide allows you to click through and determine your residency status based on your status as an immigrant, military personnel, or anyone else who may have questions about how long or when they need to reside in Colorado to qualify for in-state tuition. You can also find a list of what evidence you can use to prove Colorado residency. The guide also provides FAQs, statutes regarding tuition and residency, and a breakdown of residency requirements by two-year, four-year, public, private, and vocational institutions.
