Explain What Actually Happens During a Right to Work Check

A new employer, or your current one doing a routine recheck, asks for documents to prove you can legally work, and the process feels opaque if you've never been through it. This walks through what gets asked for, how the check actually happens, and what to do if a document is missing or the process stalls.
