Looking for advice: am I wrong to want a visiting PhD period ("visiting researcher") abroad in this case?
In my country (Latin America), it is common for Master's and PhD students to join a research topic that was already designed by the advisor, so I did not create my own thesis topic from scratch.
Because of that, I wonder whether it would be considered inappropriate or bad etiquette to pursue a research period abroad during my PhD so I could enjoy academic events, learn new techniches and get collabs on my thesis or future papers.
I ask because I already applied to one exchange call for Europe and I wasn't selected. When I applied, it felt like I was doing something inappropriate, because my PI (Supervisor) made negative comments. He did not even review my application.
I'm seeking partners in Europe without his support and I wonder if I'm wrong since my thesis topic is not really "mine".
