On the question of how long can I stay on my current visa - is that going to be 3+2 = 5 years? after which I MUST travel back to India and return only after 12 months?
a Tier 2 (Intra-Company Transfer) applicant in the Long Term Staff sub-category will
be granted leave up to 3 years with the possibility of extending for a further 2 years.
You will not be able to extend your stay beyond 5 years (or 9 years for any staff
earning £152,100 or more) and you will not be able to re-apply to return to the UK
under an Intra-Company Transfer category until 12 months after your last leave as
an Intra-Company Transfer expired or 12 months after you left the UK, whichever is
sooner, unless you will be paid an annual gross salary of £152,100 or higher.
