My husband is American citizen but he is working in UAE. We need co-sponsor. My questions are:
1. Does he need to fill I-134?
2. Does the co-sponsor have to fill I-134?
3. the co-sponsor have to fill I-184 under section 213A of the act, is it correct?

THANK YOU

1) No.
2) No.
3) Yes, and so does your husband even if his income is not sufficient/not from employment that will continue in the US.
