The United States Department of State is hiring 10 consular adjudicators to work in Rio and Sao Paulo. Please see the link to the job announcement below. Also note that I'm just passing this message along - I have no further information on the jobs other than what's listed and am not at all involved in the hiring process. Just a service to the Internations community.
Please note that due to diplomatic privileges, the jobs are best suited for Americans who are NOT dual nationals with Brazilian citizenship. Fluent Portuguese is required.
