Probably not a very good idea. I should think they'd be able to track you down. After all, a full student loan is quite a lot of money. But even if not, they could have to the moment you stepped back in the country and it'd be fraud so you'd get arrested, the whole deal. So no visiting family or friends in this country. Would you really want to be an international fugitive over it?
Apparently lots of people do skip on the payment of their loans this way. I read somewhere a while back that this is one of the biggest challenges to a steady budget.
Really though, I find it hard to condone morally. If you skip on payment you're effectively taking money out of public education and health. Don't forget that your university education is heavily subsidized by the taxpayer.
My dad said something about this the other day (as a joke to my brother as he's in a lot of debt), but you do need to be out of the country for a good few years (5 minimum i think), so it's not exactly a quick fix type thing!
You need to have left the country for 10 years for them to be cancelled I think. The counter starts over if you re-enter the UK for any reason, for any length of time.
I think your student debt is cancelled after 10 years automatically if you don't pay any of it. I know a few people who were planning on working under the threshold for repayment (15k pa) and others who were planning on not doing very much in terms of work to avoid paying fees.
I'm not really 100% sure though, this is only stuff that I've heard through other people.
Or, if you've got a problem with the system, why not go away now and get your better value education elsewhere (if it exists)? Instead of taking money from the taxpayers here and then not even bothering to put your 'talents' to use here.
But thats a point though, why would I want to go elsewhere when I can get the best education system for peanuts?
A certain moral sense, perhaps? The normal procedure is that when you go to a shop and pick up an item you'd like to have, you pay for it before it before you exit the shop; you don't just grab an item and make a run for it, just because that way you could get the television set/newspaper/bottle of milk you want for free. Likewise, when you go to a restaurant and have a nice three-course meal there, you don't run off as soon as the waiter turns around in order to dodge the bill. What you're suggesting isn't a legitimate way of saving money, it's shoplifting. Never mind about the taxpayer's money for the moment, but you'd be acting in an immoral way and not playing by the rules, so if nothing else, that sort of behaviour would be unsporting.
