They need 4 from you and 4 from the joint sponsor. It's not just 4 originals. Each form will be different, with certain sections edited differently than the first. I suggest completing, reviewing and saving your spouse's first, then edit the next three as applicable. Hint. You'll not enter 1 for your husband on his affidavit, but you will on the other three. You will show 3 children on your husband's but only two on the other three. If properly completed, the household size will populate correctly, automatically. Have fun.
