OP don’t want to alarm you, but this is not something to take lightly. It’s very rare almost never happened that petitioner got I-130 interview AFTER I-485 interview conducted. In rare occasion solo I-130 conducted ( happened to me but my case it’s not straight forward ). And usually if it’s stokes interview, the interview letter stated something about “second” interview. I think yours are different
when is this interview gonna be ? If you don’t have a lawyer, please consult good lawyer ( you can check AILA ) and just call as many lawyer as you can, hopefully u will get a lawyer that has opening for consultation asap.
call / chat EMMA during business hour. I think 8 am local time to 7 pm if I’m not mistaken to check is this real interview. This is the only time that EMMA actually useful. Say “info pass” and for the next question just say “live chat /agent” I think about 2 times / 2 questions to by pass bot.
