If you are currently in the U.S. on an O-1A or an O-1B status and you want to change your employer, you can do so, but your new employer will have to file a new O-1 petition with USCIS. You cannot simply start working for a different employer without filing a new petition with USCIS and without USCIS approving this petition.
When can I start working for the new employer?
You can only start working for the new employer once the new O-1 petition is approved. On June 22, 2020 USCIS resumed Premium Processing for O-1 petitions. This means, that USCIS will make a decision on your petition within 15 days (approval, denial, or a request for evidence). Once the petition is approved, you will be in an O-1 status and you will not need to leave the U.S. to get an O-1 visa stamp unless the petition was filed as a Consular Processing. However, once you leave the U.S., you will need to apply for an O-1 visa stamp to be able to enter the U.S. Please see our blog post on what is the difference between visa and status when you click here.
