Paranoia levels are running high here... just kidding. No, you can't tape it in video or audio. You can't even have your cell phone on during the interview. I've heard and read many things in all forums but I've never saw someone mentioning that the examiner did something wrong. The truth is that they are there not to cause you problems and they are not looking for deny you unless your application has some type of problems and in this case a good lawyer is far better than any tape. If your application is ok go there, take it easy and in the end you will see that the beast was not that bad. In my particular case, here in Miami, ALL immigration personnel were very polite, easy to deal with and my process run from beginning to the end without any hitches. You must take into consideration that thousands get their citizenship every year and most of them do not have any problems. When you read a forum like this you have the idea that problems are the rule because, normally, those who do not have any problem do not post.
Good Luck
