I was recruited by an advisor who retired midway during my PhD but agreed to keep on advising me with the help of a co-advisor. This co-advisor quit one month ago. I am currently without a main advisor.
I was on a funded three years PhD program with a low stipend in a foreign country but did not finish on time. In order to meet basic requirements, I needed two published papers and one international experience at a conference. I asked for an extension of my PhD program, which was granted, that guaranteed my visa.
Currently I have one paper officially approved for publication this month, one international experience and a paper in an R&R stage (deadline is April 8th).
The deadline to meet these basic requirements as well as finish writing the thesis manuscript appears to be the end of June if I want to obtain my PhD without asking for a third extension of enrollment.
Regarding the second article currently being reviewed, I agreed with my advisors that they would provide thorough feedback on the statistical analysis because this is not my specialty. However, when it was time to give this thorough feedback, my retired advisor did a poor job (dragging it out, extremely vague feedback, only about the form and not the content etc.). She told me that I did not have the level to write it and that I should give up on this journal. But she would not give me the reasons. So I submitted it and received the feedback from reviewers. Regarding statistical analysis, I requested her thorough feedback to strengthen my research. As a consequence, my advisor asked me to withdraw this article and submit another unwritten paper to a different journal, which would completely make me miss the deadlines to pass my defense in a timely manner. Another thing that she told me is that since I will miss the deadline, I should withdraw from the program, which would cancel my student visa and force me to apply as a free PhD candidate from my home country if I do not find a job to sponsor my visa here. I asked her why would I do that, if I can ask for another semester extension per the university's rules. She told me that after two extensions, I am "un-welcomed".
So I have several issues now.
Find a new advisor. Both former and retired advisors have been unable to convince anyone to take me as their student. I had no idea about what was happening because I was told right before the former main advisor quit.
I do not trust my retired Co-advisor anymore. I do not understand her reasoning behind the options she presents as the only ones available. Her feedbacks have always been of poor quality. It feels like she mis-represented her capacities in statistics and tried to blame it on me. I don't know what is her "interpretation" and what is the reality. I don't know if that has more to do with her inability to give thorough feedback on statistics (which she finally admitted a few days ago), and she does all this to basically avoid responsibilities and make me (the problem) disappear to my home country. Nor do I know why she does not support me obtaining my diploma as fast as possible like we agreed at the very beginning of my PhD.
I don't know if it is feasible to meet the deadlines I have mentioned.
How would you advise me to proceed?
