I look at this from a different angle, and to me the U.S. seems very welcoming to highly-skilled immigrants. They are very well-paid from European point of view, not to mention others, and the society in general is used to absorbing immigrant workers. Germany and other EU countries have expressed their welcoming attitude to immigrants in general ("Wir schaffen das"), often exaggerating the skills of people who actually had no relevant training or competence at all (plenty of quotes available for this). But the current discussion in EU about the recent immigration wave has turned into a blame game of "why does Eastern Europe not carry its share of the burden".
