Can I travel to America with a group instead of with a group?

Can't leave the group, can't travel freely. You must join this group. For example, the US delegation can only join and leave the group. If you leave, the team leader will have to report to the immigration office, which is more troublesome.

You can consider traveling directly, don't join a group, apply for a visa yourself, then design your own route, make a good travel plan and go to play by yourself.
