Spain’s recent mass immigrant regularisation stands out among other similar exercises in the EU because of its numerical size and because it has mostly concerned individuals who arrived legally under visa-free arrangements. The process has already increased the number of contributors to national insurance; it has already cost some newly regularised immigrant workers their jobs. If the pull of the Spanish labour market continues and the EU continues offering visa-free access to practically all inhabitants of the Americas, new Latin Americans are likely to arrive. The logical consequence is that further regularisations are likely to follow unless Spain enforced immigration rules and repatriated those without the right to stay.
