President Trump's plans to deport 2 million to 3 million undocumented immigrants won't come cheap.The Department of Homeland Security puts deportation costs at $8,661 per immigrant. The Center for American Progress...estimates that this figure would grow by almost $1,500 when the government increases efforts to capture more people inside the U.S.That means taxpayers may have to pony up $22 billion to $25 billion. And about one-tenth of that goes to transportation costs

As many as 25 percent of physicians practicing in the US were born in another country. Rural clinics and public safety-net hospitals, in particular, rely on foreign medical school graduates to take care of isolated and vulnerable populations. They often serve as primary care doctors, filling a vital need as more American-born MDs gravitate toward high-paying specialties.

In a year in which Republican presidential nominee Donald Trump is proposing a crackdown on immigration, all six of the 2016 American Nobel laureates announced to date are immigrants ... top scientists come to the United States because of its research-friendly funding system.

counties designated as “sanctuary” areas by ICE typically experience significantly lower rates of all types of crime, including lower homicide rates... In 2015, the typical sanctuary county in a large metropolitan area experienced 654 fewer crimes per 100,000 residents than the typical non-sanctuary county in a big, metropolitan area. That's an overall crime rate approximately 15 percent lower.

much of the backlash against immigration (and globalism) is not economic but cultural: Many people still care about their own versions of national identity and mistrust global institutions such as the EU ... rising unemployment didn’t make British regions more likely to vote to leave the EU, but a growing migrant population did. These voters were bothered less by competition from immigrants than by their perceived effect on the country’s linguistic, religious and cultural norms.

Migrants account for only 3.4% of the global population but produce 9.4% of the world output, or some $6.7 trillion. That’s almost as large as the size of the GDP of France, Germany and Switzerland combined. Compared to what they would’ve produced had they stayed at home, they add $3 trillion – that’s about the economic output of India and Indonesia combined.

Last year around 890,000 asylum-seekers, more than 70 percent of them Muslims, entered the country. Around a third came from Syria. Many of them do not want to go to Turkish mosques because they do not understand the sermons. They prefer to worship where people speak Arabic.‎ Yet in these mosques, other problems arise. They are often short of funds, or else supported by Saudi Arabia and the Gulf states. Some back ultra-conservative or highly literal interpretations of Islam, such as Wahhabism

Until 2000, people could only become German citizens if they had German blood, meaning at least one of their parents was German. That has slowly changed ... last year the German government approved its first ever integration law and pledged to spend billions on efforts aiming to avoid the mistakes of the past. But services asylum-seekers are entitled to vary greatly depending on the country they come from and whether their claims are likely to be approved.

there are roughly 1.9 million non-citizen immigrants who have been convicted of crimes and are subject to deportation — what the government calls “removable criminal aliens.” ... that total, however, includes both undocumented immigrants and noncitizens in the country legally ... there are roughly 11 million immigrants in the U.S. illegally and that approximately 820,000 of them have criminal records ... Some of those immigrants are already incarcerated

Another reason why Canadians are not worried about immigration is that they feel less insecure... income inequality has increased since the early 1980s, but it remains considerably lower than in the United States. Poverty has fallen sharply since the mid-1990s. Low-income men...are less likely to die prematurely in Canada... America spends a larger share of its GDP on social programmes than Canada does, but Canada is more generous with spending that acts as a safety net.
