AOS unauthorized work and 15+ years overstay help

* How to know if you've been placed in removal proceedings, if you weren't assigned an A number, or had any run-ins with immigration/ice?

* Should I request a FOIA or EOIR? Will the request trigger anything?

* Should I continue to work without author or quit before I send my AOS packet?

* Should I submit copies of my tax return transcripts with the I-485 to show that I paid taxes for the unauthor work, or wait until the interview to present these supporting documents?

* Should I submit my college transcript, even though I did not obtain a degree? Or wait until the interview to present these supporting documents?

* When asked have you ever violated the terms or conditions of your nonimmigrant status, should I just answer yes, give a brief explanation as to why and send the proof, or wait until the interview to present these supporting documents?

I would greatly appreciate your help.
