I've seen this film it doesn't end well.......
There is a reason for using an established mail order bride company over a random encounter. Suggest you take the legit approach!!
If this is serious and she does come over, if it is not a trap and you get win then she will be looking for a better life for herself.
How long she loves you for will depend on how long you can afford to support (pay) what she wants or until she reaches a point where 1/2 you assets + becomes a more viable option.
Soon as she can upgrade, unless you are the prime catch, she will, afterall this is overclockers.
