The major cons of legal immigration involve security risks and increased competition for job opportunities, as explained by BalancedPolitics.org. The major pros include an increased labor force, a greater influx of skilled citizens and a lowered incentive to enter the country illegally.
Immigrants flood the work force, benefiting American businesses and allowing them to increase production, writes Doug Banbow in an editorial in Forbes Magazine on the topic of immigration.
BalancedPolitics.org states that having an open immigration policy also improves the image of America internationally. Open immigration policies give the impression of a welcome country, and the ties formed when a nation accepts immigrants from various parts of the world can help strengthen its reputation in those places as well. BalancedPolitics.org adds that immigrants are often the most talented individuals in their home countries who chose to seek out greater opportunities and would make exemplary citizens.
One of the disadvantages of immigration is an increased economic burden on current citizens, reports ProCon.org. While some cite a larger workforce as a benefit of immigration, others warn that flooding the workforce with new workers would lead to wage depression for current workers and cause increased competition for Americans in an already difficult job market.
