The advantages of online dating are numerous: it's cheaper than going out to fancy restaurants or clubs, there are never "bad hair" or "nothing to wear" days on your first date, and if the date goes sour it is much easier to withdraw from an embarrassing situation by just clicking an "off" button.
Do not send her any money, offer to buy her a ticket instead. Even if she writes to you that an airline ticket would cost two or three times less in Russia (which is questionable) , do not send her the money! Most likely you are being set up for a "visa and tickets scam" when a bride asks you for money to pay for her tickets and visa and then disappears once she gets it. Ask her to provide more details on the University that she is going to come to study at, and then contact that University.
