A 4-year degree in the US is a bachelor's degree, but as they cover a major and a minor subject it takes 4 years instead of the 3 years it takes in most countries where they only cover a major subject.
As such, just your bachelor's on its own is the regional equivalent, and as no particular subjects are specified that means any bachelor's meets the requirement.
