Want to go abroad to see my girlfriend. She is in St. Petersburg. I want to fly over to see her, but I don't know what the specific process is. Just a few days.

If you stay less than seven days, go directly to the travel agency and get your passport. You can travel with a group without a visa. If you want to stay for more than 7 days and less than 30 days, ask your girlfriend to apply for an invitation letter from her Foreign Affairs Office, apply for a visa to visit relatives, get the invitation letter in about one month, and then apply for a visa in embassies and consulates in China, Russia. After getting the visa, she flew over. It's ok for your girlfriend to find an intermediary to run landing visa.
