In some ways you are very lucky because your experience of high school, hobbies and life experience will already be different from many UK/ home students so you should take advantage of this in your personal statement. But you also need to make 2 things very clear. Firstly, why do you want to study in the UK and secondly, you need to show that your English is of a good standard (usually IELTS 6ǌ or above). It is no good having IELTS 6Ǒ if you personal statement is full of grammar and spelling mistakes. But DO NOT pay for someone to write your personal statement for you on one of the many websites offering this service. If you have IELTS 6Ǒ, you do not have perfect native speaker style English and universities may reject your application if they suspect it is not your writing.
OK, I've done some research and lots of thinking, now what? Write down some ideas and topics that you think are relevant and then expand them into sentences and paragraphs. Next show your personal statement to as many people as possible to get feedback and advice and draft it again and again until you are happy with it. Always read it with a critical eye and imagine you are the admissions officer for your chosen course and ask this question: Would you give you a place on this course after reading your personal statement and WHY? _ What should I focus on if I'm an EU or International student and English is not my first language?
