Money is a legitimate concern, for both parties involved. International relationships, by their very nature, are expensive.

I've said this before, as this topic comes up every now and again, but you have to think of it from the woman's point of view. Most of the time, the woman will join the man in his home country. She will leave everything she knows behind. She will not be able to work for some time due to visa/paperwork issues, language issues, maybe her university degree doesn't transfer, unfamiliarity with the culture, unfamiliarity with how "business" is conducted, the unwillingness of locals to hire a "foreigner", etc. etc. There are a LOT of good reasons why your woman might not be able to work for some time (or ever).

So knowing whether or not you will have the means to support both of you during that time is a legitimate concern. If you want your wife to be on equal terms as far as career and income are concerned, you will probably be better off finding a local woman. She will not have any of those barriers and probably already has an established job whereas a Russian (or whomever) woman will have to start from scratch.

On the other hand, if the women you are communicating with are asking you for $10,000 fur coats, $2,000 high heels, and you haven't even met, I'd probably keep looking.
