Well, I already talked to them this morning, just explaining my situation. I'm already in the field, and I know how much my living costs are. The budget they gave me is just not realistic for the amount of time. The original Fulbright budget was way too much, true, but this one, while generous, leaves me absolutely scraping by (and I am very very frugal!). I'm basing this of two months already living here and three months here last year. And since I already started on the project, if they obliged me to stay until the original end date, I would be on 13 months of research, more than I requested. And if they start the timeline now, it would be even longer. It's not a matter of adjusting expectations for me, it's a matter of feasibility.
Anyway, I talked to Pam Jennings just to ask about these things, especially since my original start date already passed. She asked me to send some details, so I did, comparing the OG budget to what my actual expenses are and the amount they gave me. I'll see what they say.
