Recently, a few people have mentioned the new law about foreign "laborers" in Russia. Here's an explanation on someone's blog.
The reality is that mass evangelism has been restricted for awhile. I have heard about things getting "tighter," but I think it depends on what you are doing. Every once in a while you hear of a Bible study somewhere getting broken up, but I think that's fairly rare.
I haven't participated lately in anything that would be against the new proposed law. I know that authorities are especially concerned about anyone that could be taken advantage of, such as invalids or children. They fear that children are "impressionable." (I think Orthodox education of children starts pretty early, but apparently that doesn't count.)
