Colleges and universities in Colorado are seeing an increase in international students, though some schools are having a better time attracting them than others.

The Greeley Tribune reports that a study released Monday found Colorado colleges and universities say a 12.3 percent increase in international students from the 2013-14 school year to the 2014-25 year.

The increase was not across the board. Data shows the University of Northern Colorado has seen a nearly 10 percent drop in international student enrollment over the past two academic years, despite establishing programs and partnerships in Vietnam and China.

A UNC spokesman says the school has a commitment to developing relationships with international programs, but that cultivating those relationships can take years.
