How many illegal immigrants come to USA every year?
<|assistant|>
It is difficult to know the exact number of illegal immigrants who come to the United States every year, as this population is difficult to count and statistics are often incomplete or unreliable. However, the Pew Research Center estimates that approximately 1.75 million people currently residing in the United States were born in a country outside of the United States and do not have legal immigration status.
