I can't help you with the evidence they're going to want, but just to tell you about the background for those new questions in the new form, it's because they want to know if, prior to living in the US, you were ever involved in that kind of work, in case you lived in a country where human rights abuse is an issue. I don't know if you were in that line of work before immigrating to the US, but I can't see this being a problem if you worked those jobs in the US, or in the UK if that's where you come from.
Also, if you don't feel like dealing with those questions, grab the last version of the form, which does not have those questions, and submit that. You can use it until May 5th.
I just got my LA driver's license, good for 4 years, from the Lake Charles OMV. I don't yet have my EAD or Green Card.
They wanted to see...
Passport with unexpired K-1 visa.
I-797C form showing receipt of I-485 application.
Marriage certificate
Social Security Card
Overseas Driving Licence
Vehicle Registration
Proof of Insurance
I think I paid $24
I had to do the driving test and computer-based theory test. Given how easy these were, I now know why I've had so many near-death experiences on the roads here!!
I arrived just after 8am and left, with my license, at 10.30am.
Hope this helps.
