Quitting PhD for a job, how to tell advisor? I've started a PhD last year but due to financial reasons I don't think I can stay for the whole program since it's not fully funded. I've received a job offer from a very reputable company which solves my money problem &amp; looks like a promising career path. I've accepted the offer several months ago and so I've thought very carefully about it and my mind is made up.

How do I tell my university and more importantly supervisor without causing any havoc or emotional strains since they've both been very supportive so far. Another thing is that I'm on a student visa and need to obtain a work permit which requires the school's help so it's very important that I maintain a good relationship even though I'm quitting.

Thank you very much.
Whenever a professor takes on a grad student, there is no guarantee that the student will be able to complete the program.  The vast majority of people (advisors included) understand financial hardship.  

Ask to have a face-to-face meeting with your advisor.  Be honest about your reason(s).  Your advisor is likely to be willing to keep working with you as long as you are able to.  If you're worried about how to word what you will say to your advisor, something like "I wish I could have completed the program, but, due to financial burdens, I won't be able to.  I've enjoyed my time and got a lot of out the experience."  (Expand and reword as needed.)  And then give details about dates and answer questions.  If you've maintained a good working relationship with your advisor, they will likely be able to help you navigate dealing with the university.
