You can become an FBI agent after studying any subject, anywhere. The minimum educational requirement to become an FBI agent is a bachelor's degree in any subject.
Criminal justice might not be the best field of study for this career. The FBI is partial to law school graduates, Accountants, linguists, engineers, and scientists. Most of the knowledge one would accumulate in a criminal justice degree program is taught during New Agent Training at the FBI Academy. There are many applicants for Special Agent jobs, and one needs to have special skills and considerable accomplishments to be considered.
One critical requirement to become an agent is U.S. citizenship. If you studied criminal justice in Ireland as an Irish citizen, you would first have to emigrate to the United States and obtain citizenship before you could apply to the FBI.
An FBI agent must be a US Citizen.
