The Wilson Center hires two kinds of interns – research assistants (for the Center’s fellows) which are usually paid internships and program/staff interns. Each program has a different deadline for internship applications. Please see their website for full details:

Also, if you apply, please contact the IR graduate advisor Michael Williams as we have an alum who works here and he can let her know to expect a BU application.
