Accepted conference paper but changing job before the conference I am a researcher at a company C and I'm going to submit a paper as main author in the next few days for a conference next spring. The thing is, I applied to a University U for a PHD and still waiting for an answer. So in spring, I might not be in the company anymore and they will have no reason to pay me the trip and the conference. So if the paper is accepted, I can guess 5 scenarios:


C still pays me the conference (very unlikely I guess)
U pays me the conference (However this team never published to this conference so it is unlikely)
I pay for it (I don't think I would, it is really too expensive (other side of the planet))
C pays for the second author to go and present the paper at my place
My submission is cancelled


What do you think is the more probable scenario. How does Universities and Companies usually handle this? C doesn't know yet that I am looking for another position. Should I renounce publishing this paper? I have been working on that for more than a year and this is a good journal.
The only thing that can be said for sure is that the conference is unlikely to cancel the submission. I don't know of any conferences that would do such a thing. 

But whether anyone wants to pay for attendance is another question altogether. It can be explored with the company and with the university. In many cases either would be happy to help you attend as it increases their own visibility. In other cases they would not. In some situations the institution (company or university) won't pay anyway depending on the paper and the cost. 

The safest thing for you is to assume that if you want to attend then you will have to pay yourself and to hope that, upon asking, either the company or the university will pay instead. It isn't then end of the world if a co-author presents in your stead. You still have the publication on your record. 

Withdrawing your name from authorship seems to me to be the worst option as you have done the work but won't get credit. 

It is also possible that you can submit something in addition to the conference and have the university pay on the basis of that, instead.
