Do I need to cancel my visa to travel to Europe with a group? What is the cancellation method?

The concept of cancellation is: cancel the visa. Refers to the cancellation of registration in embassies and consulates in China after obtaining a visa from a certain country and returning from traveling in that country, indicating that the stay in that country has not expired. Traveling with a group to Europe is a Schengen visa, and the Schengen visa needs to be cancelled. General processing method of cancellation: 1. After the guests return to China with the tour group, the tour leader will collect their passports and boarding passes, and the tour leader will return them to the travel agency for cancellation. After cancellation, the tour group will inform the guests to collect their passports. 2. According to the regulations of European embassies at present, some guests of the team will go to the embassy for interview and cancellation after returning home, and the embassy will inform them after the team leaves the group. Guests who have been spot-checked must come to the embassy in person according to the time required by the embassy. Guests are advised to book return air tickets in the afternoon or the next day; If the day of arrival in China is Friday, Saturday or Sunday, please book the flight on Monday afternoon or evening to avoid the delay of the flight when the embassy informs you of the interview (the embassy will be closed on Friday afternoon).
