In the United States, doctoral students don't have to be a correspondent to publish their papers.

Correspondents refer to the authors on the list of authors who are responsible for communicating with journal editors, peer review and readers. Usually, the correspondent is responsible for the main work of the paper, including research design, experimental data analysis and writing.

It is suggested that when writing a specific paper, we should fully communicate with the tutor to understand the expectations and requirements of the tutor, so as to ensure that we are in a suitable position as the author in the process of publishing the paper.
