You are permitted to remain in the United States until a decision is made on your I-485.

Quibble. I may be out of date, but when 1poorlady was doing this process, you had to renew your conditional permanent resident status every two years until your permanent resident status was approved. Linked to this was the working authorization, which our company was fussy about (and rightly so). We had to keep it current until her permanent status was affirmed. We then would have had to affirm her permanent status every 10 years until she became a citizen. But we didn't wait 10 years, so never had to renew that status.
