Which program did you apply to, and was it for ETA or a full grant? I was under the impression that everyone received an in-country orientation and people going to most regions (with the notable exception of Western Europe and now it looks like East-Asia Pacific) went to a pre-departure orientation. I've been in touch with past Fulbright ETAs going to Indonesia and Malaysia and they also had in-country orientations together as ETAs before going their separate ways. Looks like I was way off the mark!
It seems like those going for research grants don't get as structured of an orientation as the ETAs though. Makes sense, since ETAs usually don't have as strong a grasp of the local language or any affiliations/connections with locals before arrival.
