Seeking a permanent job during a postdoc in a different country/continent: official and moral responsibilities I'm going to refer two countries/continents as X and Y. I'm citizen of neither. A week back, I started my third year of postdoc in X (with no teaching duties), after living two years for my first two postdocs in Y. I did my Ph.D. in X, and realized/strongly felt that apart from work, there's really no connection between X and me, whereas there's definitely very much so with Y, and I'm happy in Y, unlike X(I'm not talking work here) . One can say happiness is a choice, but I just can't force myself to like X, which I tried during my Ph.D. days, all in vein. And I trust my feelings.

My postdoc advisor in X seems to be nice, and I already told him that I'd apply for permanent positions in Y after this postdoc, and he has no problem with that. What I didn't tell him is that I don't like even spending one more day in X and I'd like to take an offer from Y now if it comes, since saying something like that would prompt the question why I had accepted his offer in the first place. I'd not have accepted had I had any options in Y, where the postdoc funding eventually ran out, and I had to find another option.

To solve my problem practically, I'll start searching for permanent jobs in Y very soon and here're my questions if you could please answer:

1) My initial appointment in X is for a year (extendable). If I can secure a job in Y, and want to leave my postdoc before that or before any significant project is completed, will that necessarily be a problem? Will either the university or the postdoc mentor be able to sue me?

2) It's a harder question and I'm trying to deal with it. Is this morally wrong not to tell him that I'm looking for a job in Y now/pretty soon (he's clearly okay with afterwards)? I understand that for now, he wants me to focus on his project only and give him something back in return because he's paying me for that, but on the other hand, I trust my feelings and feel really not good living here in X.

Thank you very much!
Postdoc advisers understand that postdocs are temporary, and that their goal is to find a permanent position. If such a position comes along -- at times we cannot always predict -- then we're generally happy for our postdocs. At least that's the case for me.

In other words, I think it's ok if you mention that you are looking for jobs and may send out applications soon. You may want to re-assure your adviser that you have every intention to continue working on the project you're on until some position can be found, as well as finish any of the work you started even if you move somewhere else. It's a waste of an adviser's resources to pay someone for work that ultimately never gets finished, but it's an entirely different thing to pay someone for 6 months who will finish up the experiments, proofs, theorems, or the writing started earlier after they moved. In that case, as an adviser, I really only paid for 6 months, but get all of the work.
