Please Advice: I peteioned for my Mother and Father and siblings, but they accedentilay forgot to list the names on line 21a on form DS230 part 1, but the did list the names on line 19). My parents received their visas and are now in America, however, my sibilings did not receive the visas (im thinking because there names were not listed on lin2 21). Bascially my sibilings should have recieved visa along with my parents so how do I correct this. any advice will be greatly appreciated. thank you.
