re: Help me understand the “pro immigration” argument

Unregulated, unrestricted immigration isn’t sound policy. People have been arguing over immigration for over 200 years. The US offers each country a number of visas each year and they are often distributed by means of an internal lottery. The lottery winners sometimes sell their citizenship. I know about 500 or more people who have immigrated here and almost each individual has a different legal status. The various kinds of visas and citizenship statuses are head spinning. I know about 3-5 people who have been deported and each of their situations were different.
Some industries are completely dependent upon imported labor and some only seasonally. The number of J-1 Visas granted for summer workers has historically been very high. The demographic of people accepting J-1’s has evolved over the past 25-30 years has changed because of economic conditions internationally. I know a bunch of people who found ways to stay permanently after initially being here on a J-1. Fake marriages are the most common and they’re big money. The going rate for girl/guy to enter into that deal is about $25k.
