Hello and welcome on board, Erik,
Please note that I have created a new thread on the Reunion Island forum from your post as the initial topic where you posted is not quite the same as yours.
Do you speak french ?
Reunion Island is a French overseas department, so you won't need any visa as you are Italian (EU National). You will have an estimate of cost of living on the following website : https://www.numbeo.com/cost-of-living/c … ry=Reunion
Try posting your CV in the Jobs in Reunion Island section of the website for better exposure. You may also search for opportunities on the following websites :
