I remember as a Post-doc in the Netherlands, I was enrolled at the University, opened a bank account and registered myself as a resident in the city hall all in less than an hour. Everything was so easy, each procedure was electronic  and in english.  It’s not the same music here in Lille. My foreigner students sometimes get trapped in administrative loopholes and when they do not master the language is not obvious how to get things done.  This is the reason why Hamidreza Ardeshiri, one of our senior PhD students in the group decided to write a How-to document to Lille 1 University.  I like to post it here for the future generations. Thanks Hamid!  The Hitchhiker’s Guide to Lille 1
