Employment Based, 2nd Interview Question

[instead1]

Hello, I have a second interview coming up for my employment based application, eb2. The interview notice asks me to bring a bunch of employment documents some if which I have already provided during 1st interview and proof of marriage.

What's confusing is that they asked for both petitioner and beneficiary to attend. Given that my petitioner is my employer, do they have to attend? Or my wife would have to? Or should I go alone?

I will follow up with my attorney but wanted to see if anyone here has any idea or suggestions.

This is the first time I read about a second interview and this requirement. If I were you I would ask the petitioner to attend too.
