I am doing a PhD and I have submitted an article to be peer-reviewed 9 months ago to a certain journal. I haven't got any response yet from the journal, their server indicates the "Under review" status. The problem is, I cannot wait more longer since the acceptance of the article is a requirement to validate my PhD.
Do you think I can stop the reviewing process and send it to another journal? What if I sent it to another journal at the same time? Or, would the reviewing process speeds up if, e.g. I pay for the open access?
I forgot to mention that the status cited above stipulates that:
At least one Reviewer has accepted to review the submisѕion, however the required number of reviews for the submisѕion have not yet been received.
I have provided 5 names for the peer-reviewing process of my article, and mentioned that 1 potential reviewer from another university should not review it (because of competitive reasons).
