What the Evidence Shows
The claim consists of two main parts: first, that undocumented immigrants do not pay taxes; second, that documented immigrants can obtain an ITIN (Individual Taxpayer Identification Number) and pay taxes.

The IRS issues ITINs to individuals who are not eligible for Social Security numbers but need to file tax returns, including undocumented immigrants. This allows them to comply with tax laws despite their immigration status. The second part of the claim is accurate in that documented immigrants and others without Social Security numbers can obtain ITINs to pay taxes.
However, the phrase "grow a brain" is an ad hominem insult and irrelevant to factual accuracy. Overall, the claim is misleading because it falsely asserts that undocumented immigrants do not pay taxes when in fact they do so extensively using ITINs or other means.
