Give me a break! Are you really buying into this spin? She's not being deported.
The parents have been here for 17 years in lawful nonimmigrant status running a restaurant/hotel (lodge?). That means they have most likely been on E-2 treaty investor visas. She is merely aging out of dependent status. She is allegedly a student and it is unclear why she did not apply for a change of status to that of a student rather than depart if she really wanted to stay here and complete her studies. Students can often parlay that into OPT and then an H1-B and then an employment based immigrant visa (some might also happen to marry a USC and switch over to a family based immigrant adjustment or remain while waiting for another family based category to become "current").
Notice that I said "depArt" not "depOrt".
Also, what is so horrible about spending time in the U.K. in your early 20's? She speaks basically the same language already and has family to stay with who will help her adjust and if she has the grades the are schools there too and she is a UK citizen so won't have to be a "foreign student on a visa". PLUS as a UK citizen she can freely come visit her parents and sister and won't even need a visa for a trip of up to 90 days at a time. Her parents have been running a business for nearly 2 decades so money for a few trips a year is probably not an issue.
What is the point of your post or that article? It's premise and titled are bogus. You bought into the propaganda message hook, line, and sinker!
