[QUOTE=Skwiskwis;1823190]You cannot stay in Russia for a year or longer without leaving the country and reentering it. I'm too lazy to check the visa rules, but there is also a limit to the total number of days you can spend in Russia each year. I visit Russia 6-8 times each year, with stays varying between 10 days and 35 days, with a business visa. When I visit other cities, and my work contacts in those cities have to register my visa, someone actually does count the number of days I've been in Russia to see if I'm in danger of exceeding the max, so sometimes at least it's taken seriously.
I rent an apartment owned by a local and shop in nearby markets, cook in the apartment, etc. Presently, it's dirt cheap for me to live here.
There are a few members who post in the Moscow section who are basically expats. You might post your question there and see what their answers are to staying in Russia long term as well.
I'm in Piter now, January 2016. It becomes dark about 16.00 and light around 10.00, so your lucky to have 6 hours or so of sunlight. If it's overcast, it can seem dark the entire day. Piter weather is notoriously unpredictable and unhealthy, as it can be cold with high humidity, and this time of year the streets and metro, busses, etc are full of people coughing and hacking. Everyone in Piter complains about two things, the weather and Moscow. About a week ago it was +7c. Today it was -25 c. Moscow is hated because, well, basically it's a dump, the people there are obnoxious, and the metro is a labyrinth full of zombies, and, more to the point, every Russian not living in Moscow resents the fact that tax money is taken from their regions and sent to Moscow to try and make Moscow look good (a hopeless task). For example, when I was in a mid sized southern Russian city a few weeks ago, everyone was bitter about the fact that their city had no money for New Years decorations, because, so they claimed, the money had gone to Moscow to decorate Red Square...[/QUOTE]I can not agree more with your impression on Moscow and SP. I just come back from SP and Moscow, and my feelings is totally same, dark clouds all day long, but I think the biggest problem is still language! You may had some misunderstands even when you buy a train ticket at ticket office if you can not speak Russian.
