The rule, as proposed, required foreign entrepreneurs to receive "significant investment of capital (at least $250,000) from [investors]" or "significant awards or grants (at least $100,000) from [the government]" to demonstrate "potential to have accelerated growth" and job creation. The entire visa is based on the idea that startups have "significant public benefit".

At the two year mark, you need to show further investment, to extend the visa three more years.

Failure to hit these numbers means your visa gets taken away.
