... is it really necessary if they only asked for driver's license in the letter?
First, let me say I have not gone through the interview yet, so I'm only speaking from reading other people's experiences here. I've noticed that the vast majority of the time, people bring extra documentation that is not asked for. But ask yourself:
- Is it "really necessary" to study the 100 civics questions? No, but you probably do anyway.
- You've spent a lot of time and money to come this far, why not be a little over-prepared?
Most of the documentation given in that sticky thread is not hard or expensive to obtain. For example, 3 year of IRS transcripts can be had for free via the IRS website. If you have a marriage license, passport, kids' birth certificates, etc, why not bring them?
Another example, I paid $8 to my state to get a copy of my driving record showing no outstanding convictions or serious tickets.
However, that sticky thread makes it sound very serious that you "MUST NEED" to bring this or that and people treat it as gospel. In my opinion that's going a little too far.
Bring what you can reasonably obtain in the time you have before the interview. Semper Paratus! And study those 100 questions.
