It seems to me, that I can give the small information to those who is going to leave for the Scandinavian countries - any country is interested in accepting the young future worker as the population of the Scandinavian countries catastrophically grows old, and there are less and less children with each year. Chances to receive visa for a woman with a child are higher, than for an absolutely lonely woman. On the experience I advise, first of all, to register a marriage in Russia and quickly to change the passport for the last name of the husband so that to the interview in the embassy in Moscow you come with the last name of the husband. Be sure, that it will help you further very much.
What seems to be important information - not every man will be waiting for you for a long time without sex. And the result can turn to be not so joyful for you. You will have great confidence of your husband - especially if you will make a correct marriage contract that will be signed on the day of registration.
Life is long, and it is not known, what will be in several years. Never agree to move to Sweden and other countries without registration of a marriage no matter what is promised to you - such situation is good only for people living in this or that country, but not for you.
What I see in Sweden: the marriages made by young Russian brides for some reason more often result in divorces - because Russian brides, basically, move not to create family but to improve the life state - and as soon as there appears a more rich or interesting man a divorce follows. And I can see it in Sweden, that the amount of men here is more than that of women and, in general, only men here wish to have family (believe me: not because there is nobody to clear the house or an apartment), and consequently, young Russian brides have a great choice of men.
But among women of the age of 40 there are almost no divorces - in Sweden there are lots of happy marriages with Russian women - Russian women of about 40 - they were already independent both in money, and in the solving vital problems in Russia, and such women move only for creating a family with the person who they love and respect, and who they know not only by e-mail...
Life in Sweden for women of 40 is much more interesting than for a young woman - meaning that her man has a firm state in life - he already has everything: work, and money, and already adult children - and he devotes the life only to the woman he lives with.
