Citizenship Interview

Went for my citizenship interview this morning. Just like on the application they still ask if I am or have ever been a member of the Communist party. If I was, which I don't think I am, would that preclude me from entry?

I had to write the sentence, "He is going to his brother's house where his sister will be too." Luckily I did well on the rest of the test and passed overall. Too bad though, as a security check is still being run on my big scary name.
