I found a job thanks to Speaking Agency when I arrived in France for my studies.
I did babysitting in English for several families in Paris. It was a great experience that allowed me to develop soft skills for my future professional life as well as meet new people thanks to their events and great international community!
They also helped me with all the paperwork and administrative things that had to be done which, in my opinion is a plus!
Bonus: They had great recommendations of things to do while I was there!
