Does Eb-1B need employer sponsorship?

Yes, unlike Eb-1A, Eb-1B requires that the alien has a permanent employment offer from a U.S. employer. Permanent job offer includes, but is not limited to, tenure or tenure-track positions. For positions other than tenure or tenure-track, the offer letter must be carefully drafted to meet the "permanent job" requirement. Click Here for a Sample Offer Letter for Eb-1B petition.
