we’ve revoked folks for less
but actually I dismiss your premise to begin with
no kids born here and being citizens and who have lived here and been educated here would not speak Ingles by aged 18.
and those born here are very unlikely to have then been yanked away till their 18th birthday to an non-English speaking environment...those would be an exception to the exception to the exception to the rule and hardly should dictate policy.....you already know I don’t think exceptions make rules
my daughters are dual Brasilian and they did not speak Ingles in Miami where we lived till later around aged 5 in kindergarten
in Texas and in the SW you will sometimes run into a Hispanic woman who was born in the States, grew-up in a Spanish speaking household and neighborhood works as a cleaning woman and does not speak English.
I have been in parts or Chicago and Brooklyn and met adults that were born in the states and hardly know English.
And then there is South Louisiana where I have no idea what they speak it is not English.
As for me, I was born in Colombia and spoke primarily Spanish until I moved to the states and entered school. My parents were US and spoke English but my siblings, maid, nanny, driver, friends and schoolmates spoke Spanish.
When I entered school in the states, I was an oddity a white boy that did not know English.
Untrue wardaddy. Just as surely as there are children who'll never leave the Bronx, there are children in border towns (where Spanish predominates) who'll never travel outside of their little sphere, and many speak only Spanish.
