"Single branch" is not a type of branch.
A branch refers to an additional location of a business, separate from its main or headquarters location.
A dependent branch is a location that relies on the head office for support and decision making.
An independent branch operates separately from the head office, making its own decisions and managing its own resources.
A foreign branch is a location established in a foreign country.
However, "single branch" is not a type of branch. It simply refers to a situation where a business has only one location or branch.
