I agree with the above comments, I think you should mention both points. Perhaps you should mention Skype as an alternative but note that you would ideally like to meet in person. I agree with you Canis, and in my experience, anthro and other social science department members are acutely aware of external factors, class, etc, and thus should not be surprised, but rather, motivated to accommodate your needs. I've always found it ironic in anthropology (and academia), we are taught to analyse and be aware of underlying factors of circumstance, yet often the needs of the students are not considered and are actually suppressed to maintain what's expected at all costs.
I'm not suggesting that every school should unreasonably coddle their students or applicants, but if they reached out to you, they should theoretically be open to negotiation on the matter!
Best of Luck! Keep us updated. I'm applying overseas so this thread is a big help.
