"Illegals" can't come to America.Sam, lets be honest. Illegals are not coming to America for jobs. America has made it impossible to run a company here so they all moved to Mexico. The Mexicans said oh shit chico we might have to get a job so they ran to the border and hopped the fence so they could get free stuff from America.
The term is currently used to talk about people without up-to-date government-authorized documentation that are in the country itself.
Not all illegals are from Mexico.
Millions come through airports to visit, study, or even work.
They become "illegal" when they forget or choose to not leave in the time allotted to them.
These people may come with infants/toddlers,
whom then end up growing up in the USA.
In nearly all cases, the parents are aware of their now unlawful presence in the US, but the minor may not be.
When they come of age and try to enter the workforce, military, or use other normal services, they generally come to realize that they are not properly documented.
