Hello, wallflower!
Just received my FPGEC too, as I am not in the US like you, we need to request for a finger print card from the California BOP. All you have to do is to indicate your address which you could do it by registering online in their website. There's a link there where you could be directed. If you have a working visa already, it would be easier for you to do your internship. As for me, I am still finding an employer to petition me. It's a hurdle for me, but, am still pursuing..
Good luck for us.
