Looking at CBO numbers, CBO reports that recent immigration into United States is drain, in particular, at state and local level since that's generally budget that gets impacted the most by people. https://www.cbo.gov/publication/61464
I looked up the source for these numbers.
It's the Center for Immigration Studies, and they are notorious for being a right-wing think tank used to dress up up anti-immigration policy using misleading statistics.
How notorious are they? Well, they are listed as a hate group with the Southern Poverty Law Center[1].
The numbers you're citing aren't 'welfare,' the biggest thing is using the education system. The thing that, long term, makes they into productive taxpayers. CIS doesn't figure the long-term benefits into their numbers because that would destroy their thesis.

In any case, none of this amounts to immigrants using less welfare than native born residents, which is what I was asking sources for.

The article also ignores state provided benefits, and thus the disparity between documented and undocumented migrant populations. The article 's "much less" headline is not really supported by the evidence provided.
