I'd rather be on the side that supports Ukraine, clean energy, and stable trade agreements. I don't feel safe in the US anymore.
If I'm to believe my Portuguese friends however, the extreme influx of digital nomad types have really changed Lisbon. There's almost no authentic Portuguese thing there anymore, just thing LARPING as it. The rent is too high for any local young Portuguese to pay for, while the landlords are super happy for these influx of wealthy expats, so the young either move out of the city or move all together.
In a very utopia like set up, there's something depressing about that reality.
When I asked about to my expat friend living there, he acknowledged it, shrugged, and said "don't hate the playa, hate the game".
Anyway, enjoy the game!
Other cities offer much better value for money and hold a lot more of the Portuguese culture intact. There are beautiful cities and towns all throughout the country.
Also, did you consider any other countries that you later struck from your list?
You can do the immigration process yourself, but it's a long process with a lot of i's to dot and t's to cross. It was helpful to have experts guiding me through the process. Learning the language also helped a ton. The Portuguese in cities all speak English extremely well, but they really embrace you when they see you putting in some effort to speak Portuguese. I learned with Pimsleur for native pronunciation and Anki frequency vocabulary decks. I had some background with Spanish, so it was easier for me to learn Portuguese than starting from zero.
I also considered Uruguay and Malta but preferred the safety of Portugal and its bigger size.
