The benefits of the migration of women to women themselves, sending, and receiving countries are well-documented. But across the world, women face higher barriers to migration than do men: in accessing the education and work experience that can help qualify them for visas, or in finding the resources necessary to move. And in some countries, women need the permission of husbands or fathers to get a job, to travel, or to obtain a passport. This is a loss to those who want to migrate and a self-inflicted wound on the countries they come from. It is also a loss to destination countries, which are denied the drive and talent of the women who don’t arrive. Recipient countries can help rebalance this inequality with a triple-win policy that benefits migrants, sending countries and themselves alike.
