Sorry to disappoint you Brian, but I myself have dealt with numerous cases of scamming in all sorts of settings and scenarios. Having the phone number means NOTHING at all, neither does any official documentation. What I strongly advise you is to use skype (it is still in use, even in the areas under siege), whatsapp, facebook and / or VK. See, if she lets you come closer to her. If she has an operating mobile, it will also be accessable to any or all of the soc nets I mentioned. Travelling to Kiev might prove difficult but Kharkov is always an option, putting the main strain of thr journey on you, but then you're the man 😉 If you have doubts or get excuses from her why things will or would not work, you can always get in touch with the admins on this site. They do a great job eliminating scammers, fraudsters and tricksters. Good look for all your endeavours!
