Removing conditions from GC but mught be changing address

[shark101au]

Hi, I obtained a conditional GC through marriage which expires 6/18/17. The good news is we are still happily married . My dilemma is I am looking to change jobs and may have an offer in a few weeks. Can I use my parents in law address to send all the paperwork in case we do move? The last thing I want is for us to move and something gets lost. What should I do?

Thanks for your help!
