Proof of whether you can open a free trip abroad and a group tour.

Free travel is not allowed to join the tour list.

If it is included in the tour group list, the visa of the tour group is signed as a whole, and all members must follow the whole tour group at the same time for entry and exit border inspection. Otherwise, the travel agency will be punished.

If the travel agency dares to take risks, it is illegal to gather people only during the entry and exit border inspection, and then the tourists go their separate ways. Because the group signing rule is that everyone must act collectively, and food, shelter, transportation and shopping must be the whole group.

As for the certificate issued by the travel agency whether to join the group, it has nothing to do with the visa, but the agreement between the tourist and the travel agency.

On the other hand, it is impossible for a person to obtain two valid visas for a country at the same time. If the group sign is valid, you can't sign a free travel, and vice versa.
