Hello, if a mother is here on a B2 tourist visa, whose US citizen daughter filed I-130 / I-485 package for mother, if mother files I-131 for advance parole, to visit her dying parent abroad, will she be allowed back into USA before her AOS interview? She has a valid B2, which I understand may become invalid due to pending I-130/I-485. Is having an advance parole pretty much a guarantee she'll be let back in here? Thanks.
