the visa i have is an HSMP Tier 1 and let’s me live, work and do whatever i want in the UK for 3 years. it’s based on points and you can find out if you qualify here (or any HSMP calculator you want to search for):
http://www.ukba.homeoffice.gov.uk/workingintheuk/tier1/hsmp/ i got the visa taken care of with some attorneys, they really simplified the process. otherwise it can take a long time (i’ve heard 6-9 months). with these guys, the hardest part was getting the paperwork from the banks, once i had it, i had the visa stamped on my passport 2 days after i turned it in. it’s a flat-rate service and i highly recommend it!
