We have the credit card, car insurance and 401k, I don’t know about the home insurance. My husband doesn’t seem concern that much and he said a lot of people don’t have joint name on mortgage too.
As lvy. said, absolutely you can travel with your non-US passport beside your valid green card. Just make sure that your trip won't affect your RFE and you will travel and come back into US before your oath date.
Good luck.
Awesome, you’re finally become finished the journey. I can’t wait for mine to be done too. My interview was schedule on 4/19. Wish my process will be as smooth as yours:)
