I just got the okay from the embassy for us to send my wife's son back to Ukraine for his interview under the K-2 section. They asked me to send a revalidation letter of my original petition. Does anyone know what this is and how it should be worded? What documents are needed with this letter? We have a list of other things that he will need for the interview but this is something new. I'm not exactly sure what a "revalidation letter" is.
