Somthing I did not notice in the various lists of documents is a detailed work history.
Not just your resume, but all the names, addresses, etc. of everywhere you have ever worked.
Also the last known status of the company. I have a discouraging percentage which are closed, sold, vanished, etc.
If things are so bad that you can't go home, and have to get a job in another state, detailed references might be necessary.
The Social Security office can help you research this, but their fees can be tricky. IIRC, if you call them, it's free. If you go in to get a hard copy, $$.
Schools you attended, including one-shot night courses. Is the school still functioning? Who has the records?
