take the life in uk test asap.
if he arrived on the 16th sept 2009 the earliest he can apply is 16th sept 2009 + 2yrs - (upto 28 days)
so 16th sept 2009 + 2yrs is 16th sept 2011
- upto 28 days is 19th August 2011
so earliest he can apply is 19th aug, the lastest is a few days b4 his visa expires (say 15th nov)
but always apply asap, so you have time to sort any problems out
