From there, Stephanie worked as an adjudications officer for US Citizenship and Immigration Services in San Juan, Puerto Rico. While there, she became intimately familiar with adjustment of status and naturalization, as well as removing conditions on permanent residence, adoption petitions, and the naturalization of minors. After leaving USCIS and working with a private law firm in San Juan, Stephanie returned to Colorado Springs, Colorado, passed the Colorado Bar, and opened the Izaguirre Law Firm in November 2010.
