you can - you ”just” need to get a non-itar job in the US, get your green card, then apply. If you are from Norway, it would probably take you around 5 years to get to that point.
Alternatively - you can get an export license for information to the particular person. Kind of like a TAA for a foreign employee. Previous employer had a European EW expert in the US office temporarily. Still not fast and lots of paperwork and limitations.
