Can children who have US citizenship support parents' green cards ?
Hi my husband I stay in US with his work Visa, E-1. We have two children who have citizenship in US and they are 4 and 2 yrs old. Can they support green card though parents are in US living with them or sill have to be over 21 yrs old to support parents' green cards ? USCIS website only mentions about the case parents are outside US.
