It went very quickly. As described in several other reviews.
Waited in line outside to let us in .... took our phones and gave us a number
Went through security and downstairs. After going through the initial people we sat down.
Note: we had two children. Make sure you have plenty of polish coins as there is one vending machine and it only accepts polish coins. This was our first full day in Poland so I had no idea how the coins worked. I had loads of bills
Went up 2 times to submit docs on #1 and take biometrics on #2.
She went up for #3 and it was the interviews. Done at a walk up window. They took her biometrics again and made her take an oath then told the children and I to sit down.
They didn't ask for chat logs, communications between family or even photos. (I did submit photos in the initial 129f package).
They asked for my tax return in the interview and I was called up to explain my job and income. (I am a realtor) I also file electronically and they initally had an issue my tax return wasn't signed. Once i explained they were ok. They wanted to keep my return but then gave it back once we picked up the visas.
