Where can I get a Russian visa in Kunming?

Just find an intermediary company. It's cheaper and more convenient to apply for a tourist visa than a business visa. You just need to mail your passport, a copy of your ID card and photos, and you can get all the tourist invitations and visas. You can come down in five working days. It's much better than taking a bus by yourself, then staying, and waiting in line at the embassy. You don't have to toss it yourself.
