Deferring admission to a computer science graduate program Background: I have the opportunity to pursue a Computer Science graduate degree at a well respected program (around top 20). I spoke with the professors at the university and I feel like I am a good fit with their research program. My ultimate pursuits are to complete a PhD in CS. I've done research as an undergraduate and it has only confirmed my notion that I want to pursue a research track career.

More background: I applied to jobs (in case I was rejected to all the programs I applied for) prior to hearing back from my respective graduate programs. I accepted a position for an industry job (this was to secure I wouldn't be both unemployed &amp; not in school).

Dilemma: Turns out my top graduate school is very interested in me, and I'm very interested in them. I would rather go to graduate school than work in industry forever. The industry job pays very well. I am split between A) working for a maximum of 1 year(It would only be 1 year, seriously I do not care about the money enough to work past a year) and B) going straight to graduate school. 

My concerns are as follows, if I choose A): 


Could I potentially defer my admissions?
If I am not allowed to defer my admissions, would I have a good chance of re-applying and being accepted a year later?
Would my potential advisers look down on me for deciding to work a year?


I already made my mind up it would be a 1 year gig if I decide A). I know some people say once you make money, you may not be able to readjust to the graduate salary pay. But I don't think that will apply to because I'm going to live very frugally with or without industry pay.
I'm afraid I have contradictory advice.


If you've been offered a funded place, there is no guarantee the funding will still be there in a year.  What you know is that you are good enough to get into a grad school, but there is a luck component too.  The school I went to told us that 1 in 10 applicants was good enough to get in, but less than 1 of 3 of those "good enough" could have places any particular year.  This is both because of funding constraints &amp; because supervisors can only supervise so many people well at one time.  So you are very likely really deciding whether to work before going through the application process again.
Nevertheless, I agree with Sylvain that it is not a good idea to do a PhD always wondering whether you would have liked industry better.  I worked for 5 years before doing my PhD, and now I'm an associate professor.  Two things make this route hard though: 1) getting used to making money (I addressed this by putting most of my salary in savings) and 2) getting used to being treated as an adult.  But there is a big win when you hit the hard parts of your PhD &amp; think "would I be happier in industry?  Nah, that was boring."  Friends that were academically stronger than but lacked that certainty had a tougher time during the troughs than I did.
