If I want a working holiday 2E visa, must I absolutely provide evidence of insurance for 12 months, even though I will be staying in France for only six months ?
Your insurance must cover you throughout the term of the visa. A 2E visa may be issued for four, five, six months or one year. For example, if you wish to stay in France for four and a half months, you will obtain a visa valid for five months and your insurance must therefore cover these five months.
