Excuse me, did the Korean delegation sign the visa paper on the passport?

In most cases, there is no sticker page when going to South Korea for group signing, only a seal, because all the information of group signing in South Korea is handed in by the travel agency, and the group signing is one or several pieces of A4 paper in the hands of the tour leader. The passport only contains the entry and exit stamps of China Border Inspection and Korean Immigration Bureau.

On the other hand, generally, only one person in a group has a passport book, and the others don't. When passing through the customs, the team leader provides the list, and the team members enter and leave the customs in order. Generally, there is a visa sticker to go last.
