Pending I485 : Employment Based - Primary and spouse living in different states

[rajeshonly]

Hey everyone.

My employment based I485 is pending and I am on H1B. I work in the state of Illinois. My wife started using the EAD since January 2017 and earlier she was in IL but had to relocate to MN in Nov 2017. We are planning to buy home in MN and settle there. But I might be working in IL for next 3-4 years. Now the biggest challenge we have is, what should we update the address on our pending I485 applications ? If we just provide one communication address of MN, we may get a question from USCIS (during interview or RFE) about this. Not sure how to handle this. Has anyone faced this issue before ? IF yes, please provide your experiences. Would be really helpful. 

Thanks in advance.
