My family came to the U.S. from Sri Lanka, and my mother was granted asylum. My father, my brother, and I were all listed on her I-589 asylum application. So, we all got asylum at the same time. That was over a year ago. Now my parents are very busy and say they have not had time to apply for a green card. But I am in college, and would like to apply for mine, and get this matter settled. Do I have to wait for them, or can I apply alone? And will it be a problem if I turn 21 before I get my green card?
