We got to embassy around 9am for a 9:30 interview. Line of about twenty people and they only let five people in at one time. We were in security and in the main buliding at about 9:20. We got a number and took a seat. At 9:30 they called us to a window. I could see my 300 page stack of documents on the other side of the window. They ask my wife for some more documents and told us to have a seat. About five min. later they called us back up. I had not done a DS-260 for her eight year old son. The lady informed us this would have to be done for his visa.We sit back down and they called us up to a different window about twenty min. later. The man talked to my wife in Russian and told her she could get a visa but her son could not until they had the DS-260. He explained things to me in English and told us if we could get it done today they could issue the visas. He said he would need to speak to her son. I got a little angry over this. I explained her son was only eight years old and did not have to be there for the interview. The first interview they questioned her son. The man spoke Ukraineing and English and her son only spoke Russian. He would not let my wife interuped and called over another women to interuped. Things were not translated correctly. He told us if we could file the DS-260 and get back before 4pm we could get the visas today. We left the embassy and were back at the flat by 11am. I emailed NVC for the ID/invoice number needed to compleat the DS-260. It was 11am in Kive and they are 7 hours ahead of east coast time. This meant we had to wait until 2pm to call NVC.I do not have internatiol calling on my phone but we had WIFI in the flat and I have SKYPE on my phone. I called NVC right at 2pm(7am thier time) and got the recording they were not opened yet. I called back 5 min. later and was put in the Q. After about 10 min. a man answered the phone and was able to give us the ID/invoice number. We filled out the DS-260 on line and summitted it. We got ready and called a cab. We left the flat at 3pm and we were back over at the embassy at 3:15. At first they were not going to let me in but my wife wanted me with her and they let me in. We went in and they called us to a window. We showed them the invoice number and he looked it up on line. They had the DS-260 and had my wife take the oath for her son and were good. Nothing like cutting it close.
