Portugal Golden Visa Guide: Pros & Cons in 2025

We are a Canadian family of 4, interested in the golden visa program. We would like to retire in Portugal eventually. Few questions on the residency versus citizenship visa program . Appears that it’s more cost effective to go for the residency visa

With the residency visa my understanding is that once you qualify , you still need language requirements. We would have to learn Portuguese?

We have a special needs daughter aged 19 - what are the pros and cons for her in Portugal?

Our other kid is 21 and needs to be in university- would she be able to acces university in Europe as a resident ?

How long does it take to get the resident visa and what are the total costs in USD involved with fees to government and lawyers etc . Also what is the minimum investment for the resident visa that is accurate? Some show 250,000 other sites show less ???

Thx
