The main driver is the H1B: https://www.uscis.gov/sites/default/files/USCIS/Resources/Reports%20and%20Studies/H-1B/h-1b-petitions-by-gender-country-of-birth-fy2018.pdf https://www.uscis.gov/sites/default/files/USCIS/Resources/Re... 73.9% of H1B visas are given to Indians, 79.2% of those Indians are males.
