If you can´t speak the language of your host country, that can ruin your trip because it is the same language which is used everywhere in that country (in schools, in enterprises etc ). Certain enterprises who traine immigrants demand a certain language level. Thus it is very important to know and understand the host´s country langauge to really enjoy your trip to its fulless and to be able to comprehend a patient when you are training in a Health domain. You are therefor always advised to learn or upgrade your language level several months before asking a Visa. The objectif is to be able to communicate with your collegues, your patients, to be able to understand your trainers and to be able to be understood by others.
