Answer:The largest reason why immigration is an economic issue boils down to resource management. Every country has limited and accounted for resources which it used to distribute as evenly as possible to it's citizens and has laws in place to keep that balance in place so as to not disrupt that countries overall economy. But when you begin to allow the influx of immigrants into a country, those resources can become to be too far stretched thin and therefore leave an issue for the citizens of that set country. For example, if a country has corn as their main food resource and it uses that corn to evenly distribute among it's citizens, it has taken into account how much corn is needed to produce each year so that way the country at sustainable levels. But if there was to be an influx of immigrants and too many people began coming into that set country, yet the government and it's own people were not adequately prepared to produce more corn than is needed for the influx of immigrants, than that can lead to inflation prices on the corn, shortage of food, etc.
