The earned income tax credits are for everyone who is low income and qualifies, not only migrants. It's a carrot to incentivize people who don't make enough money to be required to file a tax return to want to do so. Jackson Hewitt is running a little bit of a scam. While people can get many thousands of dollars back, the average earned income tax refund is only $150. So companies like Jackson Hewitt say "Hey, pay me $150 and you could get several thousand back." So the low income people are essentially tricked into filing when they didn't need to.
