My fiancee is from Lima, Peru. I speak very little Spanish and she speaks a little English. We communicate fine and are learning each others language. I am concerned that this is going to be an issue at the interview. Can any others who have delt with the issue give me some insight? Thanks.

It shouldn't be a problem as long as they can see you two can communicate with each other (of course). I don't speak perfect Portuguese by any means, nor does my fiance speak perfect English, but even when I say something incorrectly she understands what I'm talking about (guess thats just from us talking all the time).

I wouldn't worry about it at all.

Here's something you should read:

We've discussed the language issue in some detail on this thread.
