I had a student visa for one year from Sep 98 to Sep 99, but this was a 1 yr visa I was granted on arrival, they don't give that out anymore. It reads as following:
"Leave to enter the United Kingdom on condition that the holder maintains and accomodates himself and any dependants without recourse to public funds and does not enter or change employment paid or unpaid without the consent of the Secretary of State for Employment, and does not engage in business or profession without the consent of the Secretary of State for the Home Departement is hereby given for/unit _____ "
I think recently they started stamping student visas & vistor's visas for less than 6 months with the same stamp, which in my carse (1998) read
"Leave to enter for six months: employment and recourse to public funds prohibited".
For a complete list of the passport stamps and what can/can't be done, I suggest you look at:
