Ensure that the admission to study abroad is legal. Walking refers to ensuring that students are admitted to their favorite universities through specific channels or cooperation. This kind of service usually involves cooperation with overseas schools, which may include beautifying students' background, providing new student status and transcripts, or helping students enter the school through internal relations of the school. However, there are certain risks in admission, including but not limited to insufficient academic adaptability, economic pressure and illegal means that may be involved, such as providing false materials or bribing. Therefore, although guaranteed admission is legal, consumers should be cautious when choosing such services to ensure the legitimacy and transparency of the services. At the same time, we should also fully consider the potential risks and problems brought by admission.
