Rhode Island offers lower tuition to immigrants
Here, I just wanted to say this makes me happy because it shows progress in immigration law in the US. I like that since the federal government isn't making moves to pass anything, states have taken matters into their own hands. Because let's be honest with each other here: the biggest contention is more local than national.
Who knows once this is in effect and people see on a national level how progressive this law will be (knock on wood!) and show how much this will benefit the state as a whole, national lawmakers won't start to wake up to this sort of legislation and act?
What are your thoughts? Should states make these sort of decisions? Will RI serve as a guinea pig for other states?
