My mother was petitioned by my grandmother on July 2015 and the petition was approved this March 2020. She is a widow. Does the petition includes us (3 children under the age of 21 during the application, eldest now is 22 years old) even if the benificiary in the application is only my mother? Can anyone discuss to me the scope of the classificarion 203 A2B INA Adult Child of LPR. Thank you
