Writing is one of the four language skills. Writing is a helpful tool and a productive skill that enables learners to communicate ideas and thoughts in a clear, logical, and compelling way (Nunan, 1991). Writing a research project at the end of the study year program is a challenging task for many students in general. Research project writing requires knowledge of the topic and the research skills needed to compose a decent one. The present study carried out on Libyan EFL undergraduates seeks to identify perceived challenges by both students and staff. It investigates the challenges and difficulties encountered in writing graduation projects by EFL undergraduate students in the Departments of English at Faculty of Languages & Translation, Faculty of Arts, University of Zawia, and Department of English at Faculty of Arts, University of Sabratha. The current study also explores the EFL teachers’ views as supervisors about the challenges that EFL students face when they write their research. The participants of the present study are undergraduate English language students and the supervisors who oversaw their projects. The research sample included sixty-two participants and six supervisors selected from the Faculty of Arts and Faculty of Languages & Translation in Zawia University, and Faculty of Arts in Sabratha University. The sample comprises four males, and fifty-eight females. Their ages range between 20-25 years. The results indicate that undergraduate students in the Departments of English at the aforementioned faculties face a wide range of challenges when writing their research projects. These challenges span various areas, including background research knowledge, research design, academic writing and plagiarism, personal factors, and supervisory and institutional support. Supervisors attributed these challenges to a number of reasons such as practical part is absent (not practiced intensely in lectures and this makes students' writing weak), academic resources are few, writing skill is not adequate........
