I have been visiting a 48 yearold beauty from Belarus, I have been there twice for a few weeks, she wants to get visa here
We have been communicating on Viber 3-4 hours every day for 8 months with her helping me with Russian and me helping her with English. She has never asked for money, though I always bring a nice gift or so each trip. After all she drives me around between countries we visit and cooks all our meals. Am I looking for the monster in the closet here? She wishes to come visit me and sight see as she is big into photography. Thanks for help.
You're leaving out a lot... You talk about all this Viber time, then you're talking about her driving you around and cooking for you. You have already met her in person multiple times? You talk about "each trip"... that implies more than one.
Gosh man, if you have spent all this time together and you like each other and you haven't been scammed yet I'm not sure what you're asking. "Monster in the closet"?
I think there's always a possible "monster in the closet" (if by that you mean some ugly future surprise), but it sounds like you have a lot of personal time with her during which you should have had opportunity to detect any reasons for concern.
She probably can't visit the U.S. unless it's on a fiancee visa.
