Your information is incomplete.
Q1] You wrote you filed 130 for your mother. Did you also file 485 concurrently? Are you saying you got approval for 485 which is AOS?
I assume later is true, in that case there won't be any interview for your mom. If her AOS/485 is approved no question of interview.
She will get GC in the mail within 30 days after receiving Welcome letter.
Did you received Welcome letter stating Green Card is registered?
If yes, use it to get an INFOPASS appointment and get I-551 stamp in the passport which will enable her for travel.
You have not mentioned if you have received Advance Parole.
The whole purpose of Advance Parole is to make you enable for travel outside USA before Green Card is received.
Earlier, I was told on this very forum that recipient can use Advance Parole document to get re-entry in the USA if Gc is not handed over to the recipient for safety of the document. You may get some more information on it.
