Interview went well, we were approved. My fiancé said they asked 5 really basic questions and the interview lasted 3 minutes. Her interviewer was a young man with glasses, it was in Russian, and she said he was extremely friendly and welcoming. My finance was basically disappointed by how easy it was, lol. She had stressed herself out and we both prepared so much, but the hard part is already done, the interview is just a formality. I printed out tons of pictures and mounds of proof of our relationship, as well as IRS tax docs, photocopies of everything, and so much extra stuff, that absolutely no one looked at. All they wanted was the DS confirmation page, the interview confirmation page, Medical results, Financial support doc, signed form from my fiancé of intent to marry, police form with translation, and birth certificate with translation.
I have like hundreds of other pages, plus all the pages from the original submission that they gave back to us.
Not sure your route to Poland, but we got a 15 day single entry Spanish visa. However, we didn't fly into Spain, she flew from Moscow-Istanbul-Paris. She got some grief from the person at the gate in Istanbul, asking a ton of questions why we have a Spanish visa and flying into France. Thankfully, I had her bring tickets from Barcelona-Istanbul-Moscow as well as a hotel booking in Barcelona, all of which I bought, printed out, and then immediately returned. The guy at the gate took pictures of all those forms and asked for her tickets from Paris to Barcelona, which she didn't have, but she just said we were planning on buy train tickets in Paris. He made a stink, but eventually let her board the flight.
At the Paris border, the guard asked her, her plan and she responded the same as above. The guard didn't ask for any proof and just let her pass easily.
We flew Paris to Warsaw, almost no one at the airport even looked twice at her passport. Like a half a glance to make sure her name was the same as on the ticket. At the door to the airplane in Poland, there were four policemen asking to check everyone's passports. I had a heart attack thinking they were looking for Russians entering illegally, but they only cared about checking the men and waved the women through without looking at their passports.
