What it is like here
Lisbon, Cascais and the Algarve have a well-established international-school scene at European standards for meaningfully less than the UK, France or the Netherlands, in one of the safest countries in the world. The trade-off is that rents in exactly those areas have risen fast, so the cost advantage is narrowing every year.
How the process works
Secure a school place
Popular Lisbon and Cascais schools have waiting lists — start a year ahead.
Residence route for the family
The child's schooling is normally attached to a parent's residence permit rather than a standalone student visa.
