There is a big income differential; when it comes to travelling for a meeting, the woman usually has difficulty with paying expenses. If you’re meeting on neutral ground or inviting her to your country, expect to pay for her plane ticket, hotel and meals. But don’t send her cash for it, pay the bills directly yourself to protect yourself from deceit. Beware of girls who say they need to pay for a passport or for a visa, that’s likely fraudulent. My best advice - meet in a neutral place that is visa-free for her, preferably easy to access by a short, direct flight. Budget accordingly and you’ll be fine.
