Moroccan with business M that want to change it to student x2 in Korea

Hello my name Meryeme I'm Moroccan but now in Beijing I have business M that about to expire and I want to change it to student X in Chinese visa center in Korea, my question do you think it's a good idea to change my business M to student visa in Korea as a Moroccan , i already contacted the visa center and they told me if I have all the documents I can come and apply in the office , but I'm still worried if my entry permit will be rejected , so any advice ?
