question 2 mean: Export Administration Regulations (EAR), normally H1B workder from China need apply this first.
I found "What kinds of foreign nationals are exempt from the EAR?
For purposes of EAR and ITAR, US citizens, green card holders and asylee/refugees are US persons not subject to controls. However, if the technology is classified as well as controlled, permanent residents are deemed foreign nationals and are subject to controls. Persons in the US on non-immigrant visas are generally covered by the rules.
For dual nationals, the Commerce Department generally considers the last place of permanent residence or the last place citizenship was obtained to be the nationality for purposes of determining the country coverage under the deemed export rules."
But no place mentioned whether EAD holder need this or not. Thanks.
