where to send I-485 form for parents with pending I-130

[inuuniq]

Hi,

I'm applying green cards for my parents. The I-130 forms are still pending for approval. But I hope to submit I-485 form when the health exam results are ready. The USCIS website only says that parents with approved I-130 or parents who submit I-485 together with I-130 need to send I-485 to the Chicago lockbox. But how about the address to send I485 with pending I-130? Will their cases be considered filing I-485 together with I-130?

Thanks for your input and help!
