Hello, I want to ask about the Russian visa.

Russian visas are different now, depending on what visa. Now the work visa card is very strict, and it is possible to refuse it. It's quite possible. Not all previous visas can not be signed. Getting a visa invitation now may not give you a visa. International students can, but the possibility of refusal is not ruled out. Now the Russian Immigration Bureau has increased its management in this area, and the process is simple to prepare relevant documents (which is different from visa types). for reference only
