ABOUT FREE MOVEMENT
Free Movement offers updates, commentary and advice on immigration and asylum law. Our mission is to make good quality and clear information available to all affected by immigration control: migrants themselves, their families, their lawyers and their judges. Immigration law has become very complex in the UK and changes very rapidly; we try to make it simple, or at least understandable.
