Is it too late to ask the faculty for a summer research internship position? I am wondering if it's too late to ask the faculty about the availability of a summer research internship position? When would be the best time for this?

More information as requested:


I am looking for the positions in the US from May 25th onwards.
I am also a graduate student and I'm thinking of a summer internship with an eye towards the possible continuation as a post-doc.
No, it's not too late to ask. But whether it is too late to get one depends on the local situation and so we can't help with that. 

So, ask. If you don't ask you won't get one. 

There is a Chinese proverb: The best time to plant a tree is twenty years ago. The second best time is right now.
