Treaty Trader (E-1) and Treaty Investor (E-2) visas are authorized based on treaties of commerce between the U.S. and the treaty country’s individuals applying for E visas must have the treaty country’s nationality. The U.S. has also concluded treaties of commerce with several other countries.

As mentioned above, if your company is owned by a national(s) from treaty country and you are from the treaty country, and your company has substantial trade or made a substantial investment, the company would qualify for an E visa. If your company has E visa holders in the U.S. then the answer to your query is simplified. However, you still must show that you qualify for the E visa. An E visa holder may have managerial or executive duties or have specialized skills in a specific area particular to that organization. For example, an accounting position would not be managerial or executive in nature, and therefore, would not qualify for that category. If you have performed accounting in Japan for the parent company, or for a similar company in the industry, an argument can be made that you possess specialized accounting skills relative to the industry.
It is true that most E visa holders have worked for a parent company in a managerial or specialized skills position, there are no regulations, unlike the L visa that require the applicant to have been employed by the parent company.
