Coming Back to the UK from the US for School

[SinRumbo]

I have lived in the UK for eighteen years as a citizen until 2016, when I moved to America, where I am also a citizen. Now, I am 21 and wish to return to the UK to go back to university. I have my passports and housing will not be a problem, as my mother still lives in England, but I'm worried about student finance, will i still be able to receive it if I haven't lived in England for two full tax tears, what are my entitlements here?

It isn't about 'tax years'. You need 3 years residence.
