I've been in a conversation with a professor about hiring me as a potential postdoc. Recently he sent me an e-mail saying he would like to accept me to his team, but he can do this only if he can get a new grant.
As I understand the situation, his current grant is ending soon, and he hasn't been able to get new grants yet, but is still trying.
In general, when do US-based foundations announce their grant awards? (I'd like to know so that I can ask him again on time whether he got a grant, so I don't lose the position that I kind of have right now.)
