This is a complete scam - DO NOT send any money or documents !!
That's very probably a scam.

I have sent in my contract and the school has informed me that they will now process my work visa, and I need to send them the money (they will pay half) and 2 months accommodations (they will pay half.) Do schools ask for money up front from the teacher? Also, I have some doubts about sending my visa money to a personal bank account, even though the bank account is the school barrister's. Is this the proper protocol in Spain?
El Limonar seems to be a good school, but this process makes me nervous.
