That's too bad, since this is a place that looks like it'd be very interesting to work at, but with no degree there's no chance in hell I'd be allowed to work in the US (at least so previous attempts have told me), and it looks like remote is a no-go.
For what it's worth, we often sponsor VISA candidates. I don't know the particulars of your case, but we have a number of employees who have come to the USA to work for us and do everything we can to support them.
