Can my child remain in the United States if he or she turns 21 before obtaining immigrant status?
Holders of K-4 visas will be admitted to the United States for two years or until the day before their 21st birthday, whichever is shorter. The K-4 visa holder’s status will expire when he or she turns 21. If the K-4 visa holder has a pending application for adjustment of status based on an immigrant visa petition filed on his or her behalf by the same U.S.citizen petitioner who filed the I-129F, he or she may continue to be eligible for adjustment of status under the Child Status Protection Act.
