Singles entertainment in Bulgaria is very affordable with lots of good cheap restaurants.
Your money will go a lot further than in Western European countries or Moscow (believed to be the most expensive city on the planet by many...).
Bulgarian women are less likely to have professional photos; they are more likely to take a few quick snapshots with their web cam.
Many profiles of single Bulgarian girls will have low quality pictures and the girls will be much better looking in real life.
Bulgaria is much safer than Russia with much less violent crime on the streets.
Russia on the other hand is very expensive and not very safe.
Just keep in mind that their motivation for this may not be as pure as you think and you may find yourself wifeless once she has got citizenship/money through marrying you.
If you register at a Russian dating service (also known as internet dating /marriage agency) and find out that lots of much younger women are contacting you eagerly for dating - you will know for sure you have landed at a scam dating website.
Beautiful young Asian girls will absolutely readily marry men much older than themselves!
Some Russian ladies will be more inclined to seek a foreign husband for the simple reason of being less financially secure.
This does not mean that you can just walk into a Russian marriage - the Russian women are choosy when it comes to men.
Once you have met with your Bulgarian bride or perhaps Russian bride and you find out that you cannot live without each other you will consider taking her home with you.
For the Bulgarian ladies this is much easier as they can move unrestricted around Europe and more and more visit visas for the USA are being granted to Bulgarians (we have heard that some 50% of the people who apply do get them).
