She will also be asked at the port of entry.. or at least my wife was.
Did you check on the CEAC/NVC upload docs? There may be a suitable document type on the AOS side. You could also provide a cover letter (as the petitioner) explaining the addendum. IIRC, there is also an "unspecified" document type.
I'm sure your Filipina wife knows the address on record. She could answer with that, as well as provide the new address, citing the move.
My wife and I entered the US together. Port of entry was SFO. When we got to the customs and immigration checkpoint, everything appeared to be normal.. then they said, "We just have a few more questions. Follow us." We were both nervous, of course. I was allowed to go with her. They just confirmed her name and the address where she will be. That was it. They directed us down another (eerily liminal) hallway, and we emerged at the baggage claim. 🥳🇺🇸
