President Biden has proposed legislation that would legalize the presence of more than 11 million undocumented migrants now living in the United States. If the legislation is passed, most of these people will be able to seek permanent residence and eventually US citizenship. Trouble may be brewing, however. Thousands of more migrants, many of them unaccompanied children, are pouring over the southern border, overwhelming immigration detention facilities.
According to recent estimates, the United States hosts an astonishing 11 million undocumented immigrants. Not only is this number greater than that of any other country in the world, but it is also greater than the entire population of more than 100 countries, and it is easily larger than the population of any US city.
Comprehensive (as opposed to piecemeal) immigration reform would require a drastic overhaul of the statutory basis for immigration law, and it would require the support of both houses of Congress. At the very least, a comprehensive immigration reform bill would need to address (i) long-term legal status for undocumented immigrants; (ii) border security; (iii) the H-1B visa program; and (iv) permanent residency based on a STEM degree.
