Jennifer Casey is a Partner at Kolko & Casey P.C., where she specializes in the field of U.S. Immigration and Naturalization Law.


Jennifer is licensed to practice law in both Colorado and Massachusetts.  In 2006, Jennifer received her license to practice law in the Commonwealth of Massachusetts.  In 2011, Jennifer received her license to practice law in State of Colorado.  Throughout her legal career, Jennifer has exclusively practiced immigration law.


Jennifer grew up in Denver, Colorado. She attended Denver South High School and the University of Colorado at Boulder. In 2000, Jennifer received her Bachelor of Arts degree in Spanish and Latin American Studies. After graduating from college, Jennifer worked as a fourth grade teacher in a bi-lingual classroom at John Amesse Elementary School in Denver. As a teacher, Jennifer worked closely with families who recently immigrated to the United States. It was her experience with these families that inspired her to attend law school and focus on immigration law.

In 2003, Jennifer moved to San Francisco, California to attend the University of California's Hastings College of Law. During law school, Jennifer was a judicial extern at the U.S. Immigration Court in San Francisco, California. Working at the Immigration Court, Jennifer gained first-hand knowledge of how the Court functions and developed important strategies for successfully advocating for her future clients before the U.S. Immigration Courts throughout the country.


It was also during law school that Jennifer had the privilege of interning with the internationally recognized Center for Gender and Refugee Studies (CGRS). There, Jennifer co-authored an important policy recommendation report, "Getting Away with Murder: Guatemala's Failure to Protect Women and Rodi Alvarado's Quest for Safety." This report, directed at the U.S. Congress, encouraged policy makers to use their considerable influence to put pressure on the Guatemalan government to end the climate of impunity for perpetrators of violent crimes against women in that country. In 2010, a revised version of the article was published in the book, "Terrorizing Women, Feminicide in the Américas."


Following her graduation from Hastings College of Law in 2006, Jennifer and her husband relocated to Boston, Massachusetts. In the greater Boston area, Jennifer worked for several prominent attorneys in the field of immigration law. In 2010, Jennifer and her husband returned to Denver, Colorado to raise their two children at the base of their beloved Rocky Mountains. In late 2010, Jennifer was privileged to join the team at Kolko & Associates, P.C.


Since 2006, Jennifer's work resulted in hundreds of successful cases before the U.S. Immigration Courts, the Board of Immigration Appeals, United States Citizenship and Immigration Services (USCIS) and the Administrative Appeals Office (AAO).


Since 2005, Jennifer has been an active member of the American Immigration Lawyers Association (AILA) which is the primary national organization of over 10,000 immigration professionals devoted to Immigration Law in the United States. In 2013 Jennifer received the AILA Colorado Chapter New Member's Division

"Rising Star" award.  Jennifer has previously served as Chair of the Colorado Chapter of AILA's liaison committee with the Executive Office of Immigration Review (EOIR). She has also served on AILA's national liaison committe for EOIR. She currently chairs the Colorado AILA Chapter's liaison committe with the U.S. Citizenship and Immigration Service (USCIS) and is on the national AILA liaison committe for Immigration and Custums Enforcement (ICE).


In her time away from the office, Jennifer enjoys spending time with her family, cooking, gardening, hiking, skiing, swimming, and traveling. Jennifer is also an avid soccer fan.

Ms. Casey and her team were instrumental in guiding me and my wife through the daunting task of bringing her to the US legally through the I-130 process. Though the process is long and frustrating (the process--not dealing with Kolko), Ms. Casey and team provided everything we could have ever asked for and more and explained each step in the process and were always available to answer any questions. My wife and I found this firm to be fairly priced and impeccably polished for getting our legal work done. This is a 5 star immigration law firm! KC

I couldn't have been in better hands!
I felt really lucky to have fallen into the best hands. Jennifer Casey gave me a lot of confidence, she helped, guided and supported me from the beginning to end of my case. She explained every single step about the process, she is very knowledgeable and organized. She is very well prepared, she compiled all the necessary documentation and didn't miss any single detail. I believe no-one could have been a better help and guide for me. My case was approved without issue. I have no hesitation in recommending Jennifer – not only does she meet but she exceeded my expectations.

Highly recommended
Considering the huge amount of detailed information we provided to Jennifer, I was impressed with how she was able to extract the relevant and correct facts required to prepare a concise and high-quality petition and visa application. She clearly explained the process and kept us informed of progress the whole time and always responded promptly when we had any questions. Due to the quality of her work my petition and visa applications were approved without any problems or delays .
