The H-1B petition is employer specific and job specific. The H1B beneficiary can only be employed and paid by the employer who sponsored the beneficiary of the H1B petition; in addition, they can only be employed in the specific job for which the H-1B was applied. No other employment is allowed, unless another prospective employer files an H1B petition for concurrent employment, or a new amended petition is filed to reflect a change in employment with the current employer.

Honorariums to be paid by an entity other than the current employer can not be accepted by the H-1B. Only normal and customary travel expenses may be reimbursed to the H-1B for an occasional lecture, consultation or scholarly activity.
