We have already legalized in Spain with the help of immigration lawyers - on their own we would have hardly succeeded, even though we already lived here for some time - in Spain rather slow public services, they need to pull all the time, otherwise one paperwork can wait for several months. In addition, immigration experts know exactly how to issue documents, so that no problems with obtaining a residence permit, and we had nowhere to retreat - all the apartments were sold, so that either good or bad - we could not take the risk. So far, that made "non-working" residence, then the son plans to obtain the right to work: for himself or on the contract - have not decided, will depend on the situation. Residence permit obtained at once for 2 years.
Health care here is all insurance - you buy insurance and go to any necessary doctors, and you can choose even the Russian-speaking. The necessary medicines and procedures are prescribed by doctors, and we get them for free or at a great discount right in the pharmacies - not like in Russia. There are many stores within walking distance, including a Russian shop where you can buy ryazhenka, kefir, buckwheat and Russian candy. Life itself is cheaper than in Russia, although prices have risen during the coronavirus, including for utilities, especially electricity.
