OK, thank you very much.
Kindly remember that I do not get a salary here. Your positive rating is the only way I am rewarded for doing my job. So please do not forget to give me 3 or more stars, or any smiling faces, before leaving the site today. Thank you!
ANSWER: You have a right to remain as long as the I-94 allows you to, and you are fulfilling the obligations as set forth in the status that you have undertaken in the US.
Once you are in the US, the visa stamp in the passport is irrelevant to your lawful status. The I-94 governs your lawful status in the US. So as long as you keep doing what you've been doing while on E2 status, doing in terms of the E2 status, you can remain in the US until the expiration of the I-94, which is July 2018. The visa stamp expiration does not matter.
