Everything went well. Just be yourself, dress up properly and be honest.
They didnt ask me for the Affidavit of Support Anymore. I am wondering why. I asked the CO if they dont need the Form I-134 but he said. He doesnt need it anymore at this moment. Also,
He didnt asked me about the proof of relationship.
It didnt took long. The interview just took like 5 to 10 minutes only.
