I have to tell you that actually none of our clients can do it because of the financial requirement. I work in a legal aid clinic, and our clients don't meet the low-income cutoff plus 30%, so I never do parent and grandparent applications.
That being said, I know that you have had some testimony about problems before at previous meetings. I am also familiar with problems from my conversations with other members of the immigration bar. It is a problem because there is a quota. You scramble to get your application in, and you have no idea where in the queue your application may end up.
I have no doubt there are problems there, but our clients don't ever have the opportunity to bring their parents and grandparents.
