Biden opened the border with his Exec Orders.
Trump had them closed.
60% of all illegal immigration comes in through your airports and seaports, none of which were closed until 2020.
In fact, after 2017, when Trump stopped prosecuting large companies employing illegals, the number of illegal entries rose so high that Trump declared a National Emergency in 2019, to close the border, and illegal immigration went UP after he declared that emergency:

The president’s decision incited instant condemnation from Democrats, who called it an unconstitutional abuse of his authority and vowed to overturn it with Republican support.

Trump declared this NA in February of 2019, and illegal entries were HIGHEST in 2019, so his solutions to this NA made things WORSE, not better. There were 400,000 illegal crossings in 2018, and more than 950,000 in 2019 - even though Trump declared a National Disaster in February of 2019.
When did Trump close the airport and seasports???? Trump's borders were NEVER closed except in 2020, when all borders worldwide were closed to tourism and non-essential travel due to covid.
The USA has had a long, long history of providing safe refuge to people fleeing natural disasters or political instability. Since Donald Trump started vilifying and dehumanizing non-white refugees, Americans are now behaving with hatred and cruelty to refugees.
