I have lived and studied in the U.S. for over 17 years. I attended elementary and middle school as a G-visa dependent and graduated from both high school and university as an F-1 student. I have heard permanent residency applications are considered for students who have maintained status for several years (6-10?), but cannot find any official information. Are there any pathways to permanent residency for long-time resident aliens that have lived (and studied and worked) in the U.S. such as I? Thank you.
