As steven pointed out, Farris is now listed as British on both the ITF and the ATP sites. So pretty convincing proof that he's now representing the UK.
So good foresight from Jenks to give him a mention with his own thread a month or so ago.
For those wondering whether Farris is back at college or not, @BadToss on Twitter (who lives in Illinois) tweeted me this photo of Farris playing for his college team today twitter.com/BadToss/status/558752910717501440/photo/1 - he got the win that clinched a 4-0 victory for them against Green Bay today.
