We are planingplanning on visistingvisiting the Netherlands on Aug 1st1, then traveltraveling back to the US with our Dutch Citizen doughter in law, that shecitizen daughter-in-law. She was planingplanning to stay for a short visit, around 12 days, therefore she applied for the EstaESTA and the result came back with a request to interview at the US Embassy in Amsterdam!!!!!
Last week she went there anand her visa got denied!!!!!

1st question: whyWhy did she hadhave to do the interview atin the first place, and pay 165$$165 for? Bassed it? Based on the waiver system, itsit's not needed.

2nd question: What garantyguarantee from our side is needed that she will not stay in the US ?
