The debate over chain migration leans toward the extremes. The left instinctively cries racism over any plan to limit future numbers, regardless of country of origin. But some on the right fail to understand how merit-based systems can be exploited and don't recognize why we need to preserve elements of chain migration. My experience as a former foreign service officer who has issued thousands of immigrant visas tells me that we need a merit-based system that is highly selective, and a family scheme that allows Americans to bring spouses and minor children to the United States, but not other relatives.
