H-1Bs are employee, employer and employment specific
The petition we submitted to USCIS state the exact title, salary, duties, and dates of your position at the UW department or institution that sponsored your H-1B. You cannot accept any wages or honorarium from another employer unless they sponsor a concurrent H-1B on your behalf. Additionally, you cannot accept any wages or honorarium from another UW institution or department for duties outside the scope of your employment as stated in your H-1B petition. If you’d like to perform additional work for another UW department or institution, please have the additional hiring unit or institution consult IFSS. It can be done, but it likely will require a concurrent H-1B to be sponsored by the additional hiring department or institution. Filing a concurrent H-1B takes time to prepare and get approval, just like a new or extension H-1B, and will cost the additional hiring department or employer filing fees.
