We have the same or very similar travel plans

For groups of people who will be travelling together for the most part, applying for visitor visas as a group can save time. 

In order to be issued a visitor visa, each member of your group must fulfil the conditions that apply for a visitor visa. There is no guarantee that the every group member's application will be approved even though you are applying as a group. Foreign service missions have the possibility of excluding one or more members of the group if they do not meet the visa criteria.
