Alex got to the Embassy about 45 minutes before his interview. He was immediately called up to present the documents requested for in the email (nothing more than that in terms of documents).
He waited about 30 minutes then and they called him up to the second window. There he was asked four questions.
1. When did we meet?
2. Where did we meet?
3. Where do I (Lydia) live?
4. Does he plan to live in a house or an apartment?
He did his medical on June 20 (5 working days prior) so they didn't have his medical paperwork yet, but they told him we're approved pending medical and now our status is Administrative Processing!
