in 2016, 1.49 million foreign-born individuals moved to the United States, a 7 percent increase from the 1.38 million coming in 2015. India was the leading country of origin, with 175,100 arriving in 2016, followed by 160,200 from China/Hong Kong, 150,400 from Mexico, 54,700 from Cuba, and 46,600 from the Philippines. India and China surpassed Mexico in 2013 as the top origin countries for recent arrivals. Among the top countries of recent immigrants, many more Cuban born arrived in 2016 (54,700) compared to 2015 (31,500)—an increase of 74 percent. In contrast, Canadian arrivals dropped 19 percent: 38,400 in 2016, versus 47,300 in 2015.
And then the semi documented not in that list from europe:
According to Pew, between 4 and 5.5 million foreigners entered the United States with a legal visa, accounting for between 33–50% of the total population. A tourist or traveler is considered a "visa overstay" once he or she remains in the United States after the time of admission has expired. The time of admission varies greatly from traveler to traveler depending on the visa class into which they were admitted. Visa overstays tend to be somewhat more educated and better off financially than those who entered the country illegally.
To help track visa overstayers the US-VISIT (United States Visitor and Immigrant Status Indicator Technology) program collects and retains biographic, travel, and biometric information, such as photographs and fingerprints, of foreign nationals seeking entry into the United States. It also requires electronic readable passports containing this information.
Visa overstayers mostly enter with tourist or business visas. In 1994, more than half of illegal immigrants were Visa overstayers whereas in 2006, about 45% of illegal immigrants were Visa overstayers.
Those who leave the United States after overstaying their visa for more than 180 days but less than one year, leave and then attempt to apply for readmission will face a three-year ban which will not allow them to re-enter the U.S. for that period. Those who leave the United States after overstaying their visa for a period of one year or longer, leave and then attempt to apply for readmission will face a ten-year ban.
