Looking at specific national origin fiscal impact estimates, it becomes clear that among large immigrant groups, Indian immigrants are the most economically beneficial immigrant group in the U.S., with an average Indian immigrant reducing the national debt by over $1.6 million over 30 years and increasing GDP more than immigrants from any other country. Behind Indian immigrants are the Chinese, who reduce the debt by over $800,000 over 30 years. Next, Filipinos reduce the debt by over $600,000. Colombians and Venezuelans reduce the debt by $500,000 and $400,000, respectively. The most fiscally burdensome immigrants are Salvadorans, who increase the national debt by over $50,000 over 30 years, followed by the largest immigrant group, Mexicans, who, on average, increase the national debt by $10,000 each over 30 years.
