Happy Holidays everyone!

I'm putting together concurrent I-130 and I-485 for my parents and encountered two questions so far:

1. As part of the I-864 sponsorship affidavit, I need to provide income data. The form asks for the individual sponsor's income first, then the household income. My spouse and I were both self-employed; we also filed a joint return. Can I use the joint income figure from the joint tax return to fill in for the "individual annual income" on the I-864 (Item 23 and 24A)? Or do I have to separate mine from my spouse's? I could certainly do the latter but it just takes lots of time which I'd rather save if I can.

If I do use the joint income figure, do I need to have my spouse sign the affidavit too?

I haven't found pertinent information in the instructions addressing this situation.

2. Would it have any negative impact on the application if I submit an Advance Parole travel document I-131 along with the I-485 package? And in reality, is it risky to travel outside the U.S. before the I-485 approval, even if the I-131 is granted?

Thanks so much for your guidance.
