There is a leading conference that will take place in Jan 2022. Graduate students are encouraged to present a poster about their thesis work, however, the slots are limited so a recommendation letter from the advisor is needed to ensure that the student has made a significant progress in their research and is highly competent.
I have asked my advisor three times and he told me that he is going to send it but he did not send them anything. I feel like he doesn't want to send for me the recommendation letter. In the last few months I went to three workshops in the field and made new connections and I felt like he doesn't like it at all.
The deadline is very soon. I just have a feeling that he does not intend to send it "based on some history" and he is going to tell me "I forgot", he has done it before with students. So, I am assuming here that he won't send it, I am looking for anything I can do. I am hoping maybe someone who has been in my situation before can give me an idea on what to do.
Should I give up on the conference? Or should I contact the conference committee? If so what should I tell them?
I don't want to ask my advisor again.
I am in the final phase of writing the thesis.
