There has been more work in the Middle East and China (both economies are slowing down); Brazil should be picking up – large architecture firms have already established presences there. That being said, unless you have language skills that can make you able to fit right in, you might be best served knocking on doors of firms that do work abroad in these locations.
Note that few firms will post positions, even in the best of times may firms let people come to them rather than advertise – these days one ad can get 300~400 responses making the task of sorting through the material challenging.
