You should contact the Department of International Relations of the University of Chemistry and Technology Prague sufficiently ahead of your departure from Prague to find out about the documents you will need. The Department will either prepare the required documents for you to collect on an agreed date, or they will send them to the address of your home university. Make sure that you do not forget to cover the rent for accommodation for the last part of your stay in the halls of residence. Payment of all due fees is a precondition for the issue of documents on the conclusion of your exchange visit.
