Most Asian immigrants who obtain green cards—that is, permanent resident status—do so via sponsorship by family members, as is true of all immigrants. But Asian immigrants are notably more likely than immigrants from other nations to be admitted with employment visas.
In 2011, according to Department of Homeland Security statistics, 27% of immigrants from the six largest Asian source countries received green cards based on employer sponsorship, compared with 8% of other immigrants who did so. The share has varied throughout the past decade but has been markedly higher for Asian immigrants than for others.
However, considerable variation exists among the top six countries of origin. In 2011, the shares of immigrants granted green cards for employment reasons were about half or more for those from Korea (55%) and India (49%), as well as 33% for Japan and 21% for China. The shares were far lower for immigrants from the Philippines (13%) and Vietnam (1%).
