Once your exchange abroad has been confirmed, you need to start planning your stay. The host university will be your main point of contact regarding the different steps you need to take.
You will need to think about:
Your journey: How to travel? When to arrive? (In most destinations, late arrivals are not accepted).
Your budget
Your accommodation
Your visa / residence permit
Your insurance
Your baggage for a long stay
Your language skills: do you need to improve them?
