Hello everyone I am about to send off my AOS application this week. Me and my husband are super excited! Does anyone know if with 245(I) or known as "I-485A" form if I should include a explanation letter of my eligiblity as a "grandfathered derivate beneficiary alien"? I am including a copy of my mothers old I-130 which was approved on April 2 2001 that my grandfather that filed it for her who was a U.S. Citizen at the time (he has passed on) and my birth certificate showing my mothers name for "child and mother relationship" existed and also including prove of my presence before and after December 20 2000.
