Job Interview

I just got home from a "job interview" at the preschool where all of my girls went and the youngest is still attending. It went really well and the director loved me, but there may be some problems as I am not "legal". We will see, I only want a few hours a week of volunteer time, I do not want to be committed to a paying job, but there is some concern of whether or not I can even do that. I find out next week. 
It is nice that I was even able to have that experience and I hope that there won't be any issues with me having a little bit of volunteer time there, but at the same time, I wasn't expecting to even have any opportunities like this one at all, so either way, I am going to be happy!
