Interviews are conducted for N600s. Tak is wrong, again.

I assume they would at least want to see the original documents since all I gave them were copies. And maybe ask me some basic questions. But the word interview is not found on the letter I received. All it reads is "N600 and Oath" at the top and below that the time and the place. Then the list of things I should bring with me, which I listed in in the first page. Then the signature of the district director. And that's it. But I will go in expecting an interview.

federale do you have any idea what I should expect in a interview?
