Ask HN: What are your thoughts on Unshackled Ventures?

Just discovered the Unshackled Ventures - VCs who fund startups made by immigrants, and help them to get the visa and to relocate. I'm a startup founder and my life's dream is to build a company in the US, so this looks very appealing to me. But before I apply, I wanted to ask your opinion. Do you guys know about them? What is their reputation? Is this really as good as it seems?
