Every fourth non-resident foreign national in the US in 2016 was an India, according to a report which states that about 60 per cent of the resident non-immigrants were citizens of Asian countries, with those from China accounting for 15 per cent. In 2016, there were an estimated 2.3 million non-immigrant residents who are mainly workers, students, exchange visitors, and diplomats and other representatives. This was up 15 per cent from two million in 2015, said the report compiled by the Department of Homeland Security.
Examples of such temporary purposes include tourism, work, study, participation in an exchange programme, representing a foreign government or international organization, and accompanying a principal non-immigrant as an immediate family member, it said.
