Thanks for response.
I understand this is not an extension. But is the exclusion rule not applicable here and i am referring to 245 G(e) as below.
As per immigration rules
245 GB(e) cooling off exclusion is applicable as below:
" is applying under the Long Term Staff sub-category and who has, or last had entry clearance or leave to remain as a Tier 2 (Intra-Company Transfer) Migrant in the Short Term staff, Graduate Trainee or Skills Transfer sub-categories,
or under the Rules in place before 6 April 2011"
My colleague is exactly same situation ..in fact we both discussed and came to india for applying visa.
