Hi I am a permanent resident (green card holder) and have a approved petition I 130 for my spouse and 2 yrs old son both residing out side of US. Today I received notice of Action I-797 but under Beneficiary it only has my spouse's name and my son's name is missing. My son is a Derivative Beneficiary of this petition. My question is doe's notice of action only has principal beneficiary name on it? When do we get derivative beneficiary in the mix? All his details were on original petition(I130) on question 17C.
