Stay more than 3 month

I was wondering how much money a person must have per month to get permission to stay more than 3 month in portugal.

You will need to have "proof of sustenance" to show to SEF (bank statments, any assests, proof of income and such). Currently, minimum wage in Portugal is around 485€/month so you will need to proof you have that much at least per month. I hope this helps you!

Let me know if you have any other questions!
