H-1B Status is like a contract and it is specific to one employer and a range of dates as listed on the I-797 Approval Notice. In order to remain in legal H-1B Status, the foreign national must maintain each element of the original application:
If the hiring department wants to change any of these conditions, they must consult with OIA first. In some cases, an entire new H-1B application and fees are required to make changes in the employment.
H-1B foreign nationals may not accept compensation, including honoraria, from any other employer or entity other than those named in the original H-1B application. Foreign nationals in H-1B Status who are invited to give a lecture off-campus, collaborate or conduct research with other schools can receive reimbursement for reasonable living and transportation costs only.
A foreign national may work for more than one employer, but each employer must file a separate H-1B application.
Finally, it is important to note that all non-immigrant visa holders are required to notify USCIS within 10 days of a change of residential address. H-1B visa holders may report a change of address by completing Form AR-11 or Form AR-11SR. You can update your address on this Web site.
