She got the first GC when she was just a kid I think 5 or 7 years old, long before father and stepmother divorced. I think she initially entered on a IR-2 then, which is why her current GC category shows IR-2. Will get some more info from both father and stepmom.

Thank you @Mike E I suspected the same too, about the clock resetting to 2020. I am also trying to gather more info from my friend (let's call her Jane D) who is in this situation. I am not sure and highly doubt an adoption was made by the U.S. citizen [stepmother]. The stepmother was married to Jane D's father for several years and lived with him [and raised Jane D] in ForeignCountry before returning to the U.S. and later [amicably] divorcing Jane D's father. Jane D's father was not interested in and did not seek U.S. LPRncy or naturalization. After divorcement, they remained close and the stepmother returned to the U.S. with Jane D when she was well below 10 years old, for about 1.5 years. However, Jane D returned to NativeCountry and completed education up to high school there, before coming back to the U.S. to live with her stepmom and attend University [in 2020].

Background Info: Step-child of U.S. citizen Original GC issued in 2008 (Current GC indicates residency since 08 Absent from U.S. for more than 6 months quite often prior to 2020 Current GC renewed in 2021, and expires in 2031 Now in the U.S. and attending University as a LPR Original GC issued when holder was under 18, but is now over 21 Question: Does an IR2 GC holder need 5 years of continuous residency, or can this GC holder apply for naturalization (N400) now? Or should she file for a Certificate of Citizenship (N600)? Will appreciate any info from those who might have had a similar case.
