To look at Immigration and understand a broader look is required than just Biden vs Trump. Also all types of immigration need to be evaluated. The attached link will take you to a visual chart that has it's methodology and how they classified the numbers from Congressional Budget Office (CBO) under it. I did my best to cut and paste an excerpt. Under Biden Illegal immigration was the highest by far.

This chart shows net immigration figures in the U.S. from 2001 to 2024, broken down by immigrant status. Data for 2021 to 2024 are projections.

The CBO categorizes immigrants to the United States of America into three groups:

    LPR+: Lawful permanent residents (LPRs) plus people who are eligible to apply to become LPRs on the basis of their current status, such as asylees and refugees. LPRs include those who are granted that status while within the United States as well as people who have gained admission from abroad.

    INA nonimmigrant: Comprises temporary workers, student exchange visitors, qualifying family members, and others admitted as nonimmigrants under the Immigration and Nationality Act (INA)—for example, officials of foreign governments—while they remain in that status.

    Other foreign national: People in the U.S. who are not in the first two categories and who have not subsequently become U.S. citizens or received LPR, asylee, or nonimmigrant status—such as those who entered the U.S. illegally or those who entered legally in a temporary status and then remained after that legal status expired
