Iv been asked to provide verification for legal work in USA. how am I to respond?

You provide work authorization, visa, or green card to show you work legally in the U.S. If you're unsure what specific documents are required, ask them for clarification.

Just give them the required documentation to verify your legal work status, such as your work visa, employment authorization document (EAD), or green card. If you're unsure, consult with your employer or an immigration lawyer for guidance.
