What would be the path to AOS for a U4U parolee (currently in US) who is a sibling of a USC with I-130 already approved (waiting on visa number)?
Edit: answered my own question
"In general, if you are filing as a beneficiary of an immigrant visa petition (such as Form I-130, Form I-140, or Form I-360), you may file an adjustment application only after USCIS has approved your petition and an immigrant visa number is immediately available."
