Strange !! Tier 1 Transitional 2 years ?

Recently, with hsmp approval letter i applied the hsmp Under Tier 1 Transitional arrangement, and the visa was stamped 2 years and visa type specified in passport as Tier 1/HSMP. When i referred back to embassy, they said the Entry clearance officer decided give only 2 years instead of 3 years.

Its Strange, whether Tier 1 is Generic across the world interms of Validity?
Can i appeal back? is there any problem.. pls suggest.

How long was your initial HSMP valid for? 2 years?

I've been told by my local visa application centre that it will be for two years in cases such as these. It is strange indeed.

According to pg 9 on http://www.ukba.homeoffice.gov.uk/sitec ... yguide.pdf it should be three years? Or am I misinterpreting it?

bsa099, were you told that you have to apply for EC and enter the UK within the 6 month validity period of your approval letter? That's what they told me.
