Come to the appeals thread. I know one lady Galano123 win her ADR. So there is no calling witness there. But her spouse is Cuban.
In my case my husband & I thought maybe an arabic interpreter could help with answering questions correctly for IAD. However we changed our minds. Before the appeal. And as it turns out they called the interpreter anyhow. Her Arabic was Lebanon. Way different then Moroccan. Thank goodness we don't use her. I always told my husband he spoke better English than most immigrants. They talk with both of us about 20 to 30 minutes. Sorry to hear you got refused. But you can win with good proof.
