IELTS (International English Language Testing System) is widely required for student visa applications in English-speaking countries like the USA, UK, Canada, and Australia. It assesses English proficiency in listening, reading, writing, and speaking. Most universities require an IELTS score between 6.0 and 7.5, depending on the program. Some countries offer exemptions if students studied in English previously. A good IELTS score improves visa approval chances, as it proves language ability for academic success. To apply for a student visa, applicants need an admission letter, financial proof, and other documents. Proper preparation is essential to achieve the required IELTS score.
