Interview : 19 May 9h30
Post : Madrid
We got at the embassy at 8h30, there was a large queue and they told us to wait in the queue, then a lady came asking every person what their situation was, and she told us to come back at 9,9:15. So we did, and we passed directly inside without queueing.
We passed the security check, they took our phones, and we only had our documents with us as they didn't allow entry with other bags or backpacks. We had left those in a coffee place across the street.
We passed another queue and we were handed an envelope on which we were asked to write our names, address and phone number, then took the envelope and gave us a number.
The room was quite small and there were a lot of windows, so we were quite confused but a lady informed someone at one of the windows that we were there for the dv lottery visa and told us to wait, to not mind the queues, and told us we will be called.
Soon enough we were called to one window where we were asked to produce the documents. The lady was Spanish and didn't know very well the documents that she needed but she had someone instructing her. She took all our documents and then told us we need to send them a more recent French police certificate. (I had lived in France 4 years ago and obtained the certificate in 2021,but had since been back in France for 2 short trips.) lucky I had foreseen this and obtained a new certificate 2 days before the interview which I hadn't even managed to translate, but they luckily accepted it!
Then we went to pay at the counter, in euros (if you pay in cash you need to have exact change, which we didn't so we needed to go out, change and come back)
We then gave the receipt to the 1st counter and the lady informed us where we need to wait for the interview.
We were finally called at the last counter where a nice American man made us take an oath, took our biometrics and then asked 2 questions - where did I study, and to my husband, what does he work as.
Then he said, well everything looks good to me, so your visas are approved, and gave us a white paper that said welcome to the United States. My eyes were full of happy tears by this moment and the CO was smiling ear to ear, told us we can expect our visas in 1-2 weeks.
That was it! Didn't ask for any bank statements or i-134 although we had them prepared.
Good luck to everyone here, overprepare always and be confident that things will turn out good!
