I interned for one of the National Labs this past summer. So, I've been in constant contact with them since I interned with them. Last time I spoke with one of my lab connects he said that they would sponsor me. Depending on my graduate school choice of course. But, I've been rejected to 2/4 of the schools I applied to. The other 2 aren't looking too good. If I get rejected from both, it will throw me out of the running.
