Hope I'm not joining to late in conversation but as someone from Portugal I can say the LGBTQ+ situation here is quite OK, people are tolerant and if you go to a big city like Lisbon or Porto you can find lots of community support.

The weather is also nice, winters and short and the temperatures are mild most of the year, even though it can be really cold for a few days in the winter. Summers can be tough due to the intense heat but there is AC almost everywhere and near the coastline its more tolerable.

As for immigration things have been better in the past and there is starting to be a bit of resentment for immigrants, especially those with lots of money that contribute to make life more expensive for the folks living here. The immigration laws have also been tightened and there were some changes to the entities regulating immigration, I advise you to look for information at the AIMA portal and see what applies to you.
