I was wondering if anyone knows exactly what documents will be needed for the interview for a K-3 in Peru? I have the I-186 and the DS-230 all filled out and hoping that is all. I know the K-1 has a lot more and trying to look at the Embassy info page on the site here and so wondering if need to do the DS-156 or what more documents to fill out will be included in the 3&4 package. On the Embassy's page they have a special online link on where to make filing out the DS-156 easier: https://evisaforms.state.gov/ds156.asp?lang=1

Our application is at NVC and I'm about to go back to Peru this week so wanted to get everything done now if possible so it is ready for my wife.
