I don't see how any kind of vulnerability or being widowed, among other things, would make it less likely that an individual would be granted a super visa. The requirements remain the same. Therefore, I don't see how vulnerability would make it harder to get the super visa. To be able to comment on this, I would have to read, review and assess the attorney in question's report.
I don't know if my colleague Mr. Seyler wishes to add anything.
