IntroductionMost foreign students worry about the difficulty of writing essays in English. Therefore, foreign students face a huge challenge in how to learn academic writing, who always encounter many problems related to academic writing, such as lack of vocabulary, insufficient grammar and disorganization of paragraphs. According to Harris (2010), there are many differences between non-Indigenous and National students in terms of grammar and essay structure. Others argue that writing styles and convention culture are the main problems (Sondek, 2008, cited in Linn, 2009). This essay will suggest that insufficient grammar, limited range of vocabulary and conventional writing, as well as different writing styles, constitute the most significant differences between foreign and domestic students.Language problemThere have been a remarkable study that international students generally have problems with academic writing in English due to lack of vocabulary and grammar. Holopainen (1997, p.119 cited in Harris, 2010 p.67) states that “grammatical and lexical inadequacy” generally leads to failure in essay writing among international students. Harris (2010, p 67) argues that there is a difference between UK and overseas students, with UK students rarely making grammatical errors compared to overseas students who always reverse sentence order. In contrast, Linn (White (2001) cited in Linn 2009, p2) argues that international students fail in academic writing due to weak grammar. The use of metaphorical languages ​​in academic writing, according to Harris (2010), is noticeable. difference between British and Romance/Russian and Oriental language students...... middle of paper ......ular, low levels of grammar and text content. The reason for difficulties in academic writing among foreign students, who are not familiar with the style of English writers, different culture and new environment of British universities. As a result, international students often do not reach the standard of expectation of the British academic reader. There are limitations in both articles on Linn (2009) and Harris (2010), which do not include referencing style, plagiarism, and small number of students. exclude immigrant students. Recommendation for international students wishing to study in the UK should learn about the principle of academic writing, for example: word connection, number of paragraphs, metaphorical usage, linear structure and deductive style. For this reason, governments and the community must work together to prepare students for future university studies..
