If you want to transfer the league organization from your original school to your university, you must have a league member file. If you don't have a file, strictly speaking, it doesn't affect your university registration. Only according to the league's articles of association, if you don't leave the league for more than six months, you will automatically leave the league and no longer be a member.

However, as young people in the new era, we should actively move closer to the league organization, and we will move closer to the party organization in the future. So the alliance is still very important. I suggest that you have a league member file when you apply to college.
