Accommodation declaration for Malta

Hi can anyone help me. I am applying to go Malta from England on work placement for 3 weeks and the college is funding the trip. The accommodation which will be at a university residence will also paid for by the college also. At first I was told I can submit confirmation of flight and accommodation as a copy. Who needs to fill the accommodation declaration form (if I need it) and also do the university need to send all those supporting documents - proof of residence, proof of income, hosts ID card etc. This is kinda confusing and I cant speak to anyone on phone about it...its all in writing which is taking forever. HELP PLEASE!

I'm sorry but your question is confusing. Who needs what and submit what to whom? Please be specific.
