My wife and I are in the US. She has a B-2 visa and we plan to change her status to O-3. USCIS is supposed to send a new I-94 form after approving a change of status.
After changing the status to O-3, if my wife leaves the US and enters again with the B-2 visa and the new I-94 form, will she get a O-3 status? Or must she apply for a new O-3 visa in a US embassy before entering the US again?
Surprisingly, the answer I get from different sources (USCIS and attorneys) are completely different. The attorney says my wife has to apply for a new O-3 visa, but several USCIS representatives (via USCIS website chat) told me that she would get an O-3 status with the B-2 visa + I-94.
