The solution is an easy fix for Congress
The solution IS an easy fix. Doesn't even need Congress.
And you might ask yourself, if it's easy to fix, but isn't fixed -- why is that?
The answer is that it is intentional. There are groups of people who want it for religious-like or ideology reasons, some for monetary reasons, some for political reasons.
Illegal immigration is funded by parts of the US and other governments. Such as:
-- $ from the US (DHS, FEMA, etc.)
-- To pro-migration NGO's (UN, HIAS, UNICEF, Catholic Charities USA, Jewish Families Council, Red Cross, International Organization of Migration, Doctors Without Borders, etc.)
-- To migrants ($ in cash, vouchers, cash cards, food, info including maps showing where to go, where to get money, which border crossings to use to get into the US):
