In a CV, how do I list my status of a PhD if I completed the oral exam, but not awarded officialy?

I was advised by my supervisor that on completion of the viva, I would be informed immediately (orally) of the outcome, and from that point I would 'officially' hold the PhD qualification.

The corrections/amendments and the committee/Senate meetings are effectively rubber stamps, providing you actually submit the corrected version.

And so in your position I would state that I have achieved my PhD on the date of the viva within my CV.

I don't know if there's an "accepted form", but when I was in this situation I simply noted in brackets "Viva passed, graduation expected $date".

The way you describe your status in your CV should probably depend on where you are sending it. If you're applying to a UK institution, you can explicitly say that you "passed the viva with minor corrections"; for a European institution or a private company you'd say something more vague like "defended the thesis".

Now, depending on where you're applying, they may or may not be able to hire you before you make the corrections and get your official award. UK universities will normally hire postdocs that are still waiting for their award, but will pay them a smaller salary. In France, on the contrary, you normally need to be awarded your PhD before you can sign a contract (but thankfully, you don't need to wait for the award ceremony). Private companies, obviously, can do whatever they want, but I don't see a reason for not hiring someone who has defended and does not have much else to do.

For the overseas students, there's also the question of correctly switching from the student visa to a work visa, but I don't have up do date knowledge on that.
