I-864 Help!!!

[jlong 0]

Hi, I am filling in I-864 and have four questions that I was hoping someone could answer. I actually sent the package last week but managed for USPS to intercept and send back once I realized I made some mistakes on the following areas.

1. I had a change of jobs mid way through the year. How do I show this on my current annual income? What I thought of doing was taking my year to date of pay from previous employer and adding it to expected income for new employer based on weekly gross pay. I have a letter from current employer, previous employer, and pay stubs.

2. I am have enough income to sponsor my dad, but I know that it might be beneficial to get my wife to fill out I-864a, will this be ok even though my income is high enough?

3. We filed taxes on 1040 and 1040a, i presume we put total income from out tax transcript for all the years even though we filed jointly. I have included W2's and 1099s in our package.

4. My wife gets Social Security Disability (like I said my income is high enough). Do I use the pre deduction amount or post (net).
