As a PhD student (in the US), should I always discuss whether I should go to a conference or summer school with my advisor before I apply? Even if
- The conference is providing full financial support, and
- I am not currently employed as a research assistant (rather teaching assistant) and the conference wouldn't affect that.
I realise it is common courtesy to do so anyway, but is it still OK if I don't?
Please don't answer to tell me what the "rules" are, or with "why don't you want to tell your advisor about it". I'm rather looking for a practical answer.
