您好，不好意思我沒有說清楚， 您說的1040 item 11 是我和我先生聯合報稅的家庭adjusted gross income, 但是現在我隻用我個人的自雇收入為父母擔保，我先生的收入低也不用他填864A, 這樣的情況， 是否864裏還是填家庭adjusted gross income? 或是應該按我個人的personal income填, 也就是 1040（schedule C） 的 gross income 還是 net profit 呢? 多謝指點！
-It should be the net profit, the amount in Line 31 of Schedule C, i.e., the amount you reported in Line 3 of Schedule 1 of 1040.
You need to provde the copies of all the schedules of 1040 including Schedule C with the copy of your tax return (joint tax return).
Another calculation (better way): you can subtract your spouse's income from the amount in Line/Item 11 of 1040, then the left amount is your adjusted gross income and then, put this amount in your I-864.
