Because we only make personal introductions. So we always know which ladies are available and those who are not. If a lady is already in correspondence we do not send out her details or make further introductions to her. Let us know immediately and we will investigate for you. We do not tolerate insincerity and any lady found being insincere will be expelled from our agency.
Most Russian ladies learn English in school.
Of course after leaving school many don't use it again. So the levels of English can vary. But once introduced all ladies make a big effort to learn English. Our experience has shown that language is only a problem if you make it one . Show a little kindness and understanding, and working together to overcome the language barrier will actually help to bring you closer together.
