We didn't see this programme, but we have heard about it elsewhere and posted a response, which is probably worth repeating our thoughts here:
"The visa issue has become extremely thorny in recent years, and the authorities don't seem too keen to unravel some of the rather arcane requirements and red tape. Having said that, if you get good advice in the first place, the problem of re-issuing visas (and having them rescinded) shouldn't arise. Unfortunately, there are people who have been badly advised and some who have been taken advantage of by unscrupulous companies who claim they can set up business visas at the drop of a hat. The simple truth is you should first consult a specialist immigration attorney (there is one we use all the time in Orlando) and then look at your finances.
As regards buying property, it is actually the ideal time to be looking to buy in Orlando, as it is a classic buyer's market just now, with plenty of stock and a stagnating price situation. If you are looking for a short-term investment, this is NOT the thing to look at. But, for a good long-term bet, Orlando property is still very good value, as long as you don't expect to make a lot of money back in vacation rentals. There is simply too much capacity in some areas, and the UK market isn't enough to fill up all the capacity. This situation WILL change in the next few years as more of the American domestic market discovers the great value and style of staying in a vacation home. At the moment, the vast majority of domestic visitors still use hotels, but the word is out about staying in homes instead, and you can expect this to become more prevalent in future."
