An EAD (Employment Authorization Document) allows temporary work permission, while a green card grants permanent residence and broader rights in the US.

EAD is temporary, typically valid for 1-2 years, and specific to work authorization, whereas a green card provides indefinite stay, work freedom, and potential path to citizenship.

A green card offers permanent residency, freedom to work anywhere, travel flexibility, and eligibility for citizenship, whereas an EAD only provides temporary work authorization, often tied to a specific employer or circumstance.
